Are cockroaches really "dirty cowhides"? Experts have studied that cockroaches are actually cleaner than humans, and they wash their bodies at any time; and cockroaches are very "humble" and they leave when they see people coming.

Lin Jindun, a professor at the Department of Life Sciences at Taiwan Normal University, and the "Cockroach Family" teamed up with students to shoot the "Secret of Cockroaches" science education documentary. It stood out last year in the "Blooming Real Taiwan" documentary selection program jointly with the Executive Yuan and the Global Headquarters of National Geographic Channel, and will be broadcast in 145 countries starting this month. The global premiere will be held at the Normal University tonight.

Cockroaches are almost "must kill" insects for humans. However, Lin Jindun, who has been studying cockroaches for many years, said that cockroaches are actually more qualified to be called "native people of the earth" than humans. As early as 300 million years ago, the ancestors of cockroaches appeared on the earth, while humans only appeared 2 million years ago. There are more than 4,000 cockroaches in the world, most of which are born in the wild, and only 7 or 8 species are hated to the core.

In the documentary, the audience will find that cockroaches are actually cleaner than humans. In addition to sleeping, eating, etc., they are focusing on cleaning their bodies, including important parts such as tentacles, six feet or tail hair, to maintain sensitivity on the body surface. Careful people will find that cockroaches will use their forefoots to pull the tentacles to their mouths, and then use saliva to clean the 175 sections of the tentacles in sequence. Lin Jindun revealed that this action is more sophisticated and clever than when the King of Gezai Opera Sun Cuifeng sings Mu Guiying.

Lin Jindun pointed out that people who say cockroaches are bad do not understand cockroaches. Cockroaches are beneficial insects, not pests. They only have the responsibility of the remover to clean up debris and be neighbors with human kitchen waste and messy environments to conflict with humans. But cockroaches are quite modest. They leave when they see people coming, just move away from humans that smell bad and moldy. Why do humans have to chase and fight hard?

After reading "The Secret of Cockroaches", "You will not see cockroaches again, you just want to step on him and turn ninety degrees and beat him to death." Lin Jindun patted his chest and promised.

Are cockroaches really "dirty" cows? "In fact, they are cleaner than humans and clean themselves up at any time; they are still very modest, and they will automatically avoid them as soon as they appear." Yesterday, Lin Jindun, a professor at the Department of Life Sciences of Taiwan Normal University, helped cockroaches exude their resentment for 300 million years through a documentary.

Lin Jindun has been studying cockroaches for 15 years. He said that in addition to eating, sleeping, and working, cockroaches will clean their tentacles, six feet or tail hairs when they are free to maintain the sensitivity of the body surface organs. In addition, the smooth chitin of the cockroach exoskeleton also makes it less likely to get dirty.

He emphasized that the dirty environment in a human place will attract cockroaches. Instead of judging themselves, people blame the "clearers". It makes no sense. If cockroaches don't help clean up, garbage made by humans is more likely to become moldy, foul smell, reproduce microorganisms, pathogens, and harm all living things. The odor on cockroaches is actually a sacrifice. "Like a hard-working cleaner, can you ask him to wear a suit and tie when working?"

Lin Jindun pointed out that cockroaches are ecological removers and food chains that are stable. In addition to removing small pieces and preventing them from becoming bacterial toxins, the excreted feces can be used as plant nutrients and also as food for birds, frogs, spiders, etc. Cockroaches are rich in protein. There are restaurants in Pingtung to fry them as food, and there are three medicines in Yunnan to treat heart disease.

Why can cockroaches exist 300 million years ago and not be eliminated? The documentary shows their superior survivability. They are the scues in insects. If the speed of adults running is 320 kilometers per hour, a female cockroach can give birth to 10,000 offspring, and it has a unique valve that will make them unable to die. It is okay to live for one month without eating or drinking. With water, you can last for three months, and you can live for more than 38 hours after exhausting the air. Cut off your head and your feet will move after a week.

Lin Jindun said that there are more than 4,000 existing cockroaches, most of which are born in the wild, and there are 75 species in Taiwan. The only types of cockroaches that live with humans are American cockroaches and German cockroaches. Over the past 300 million years, cockroaches have not changed in appearance (half smaller than 8.9 cm smaller than fossils) and flattened (easier to hide), which is what he admires the most.

The aforementioned information of the documentary "Cockroach x Files" reminds people of the correct attitude towards cockroaches. Although some people say that cockroaches are infected with more than 40 diseases, Lin Jindun said in an exclusive interview with the Central News Agency that all organisms carry bacteria, and the number of bacteria in humans in their mouths is as high as that of people around the world. When avian influenza comes, humans kill all birds, dengue fever comes, kill all mosquitoes, crazy cow disease comes, killing cows, rabies comes, and killing dogs, but AIDS comes, but not killing everyone.

Therefore, he hopes that people will understand more with the attitude of respecting the lives of all things, tolerate cockroaches, and even learn the way of survival of cockroaches with modest and low-key.

Talking about the origin of his relationship with cockroaches, Lin Jindun said that when he was a child, he was in the countryside and his family was poor. His brothers often ate roasted cockroaches, which were very fragrant and delicious, making him full of gratitude for cockroaches. Later, he studied biological research based on nerves, and used cockroaches as the object to study cockroaches' behaviors that have survived 300 million years ago to the present. He specifically asked the Central Academy for purebred American cockroaches and research on animal house cultivation research at the Taiwan Normal University branch. At most, there were more than 2,000, and now there are more than 500.

He said that cockroaches have two major compound eyes, two single eyes. Everyone thought that single eyes were degenerated. He found that cockroaches had the function of distinguishing light from sight, which can assist compound eyesight. Color, depth of field, and three-dimensional can be seen in the dark, which is helpful for escape. In addition, the two tail hairs at the back each have nineteen sections, and each section has eleven sense hairs, which can feel airflow. Therefore, people can see it from the front, single eyes, and hit it from the back, tail hairs are easy to feel, and they are easy to escape.

With respect for cockroaches' lives, Lin Jindun set up a "cockroach nursing home" in his puppy house upstairs. He detected sick cockroaches on the road. After the experiment, he brought them back to the "cockroach nursing home". He also took them to the "cockroach nursing home". He ate dog feed, regulated the heating and heating, and waited until he was naturally old.

He taught by example that students who wanted to do cockroach research with him would catch a cockroach first and put it in his hands before joining the cockroach family for research. He was also very glad that some middle school students in central and southern Taiwan often asked him for cockroaches to do scientific research.

Despite this, Lin Jindun believes that he is not in-depth enough to study cockroaches. He hopes that young people will continue to study cockroaches, from physiology to extensive applications, which are worthy of research, and may even benefit humans.

Screaming, picking up slippers and hitting hard seems to be the standard reaction when we see cockroaches in daily life. Not only are rats crossing the street and everyone shouting and beating them, but as one of the insects that are common in human living environments, the fate of cockroaches is often not much better. Why hate cockroaches? When asked this question, I believe everyone can list several reasons: dirty, infectious diseases, looking nauseous... etc. It seems that cockroaches are the best synonyms for uninvited guests in everyone's mind. However, is this really the true nature of cockroaches? Or is it our mistakes about it all the time

Answer? In the "Blooming Real Taiwan" series of videos jointly produced and broadcasted by the National Geographic Channel and the News Bureau a few days ago, four documentaries that can represent the spirit of Taiwan were selected. Among them, the "secret of cockroaches" was planned by Professor Lin Jindun, the "authoritative cockroach" of the Department of Life Sciences of National Taiwan Normal University. Professor Lin, who has been studying cockroaches for 16 years, can be said to be at the point of being with cockroaches every day. He even said: "Cockroaches are my nobleman!" He is determined to wash away the "stigma" of cockroaches for 300 million years. Today's great figures, let's get to know cockroaches you don't know!

National Geographic Channel: "I never knew cockroaches were so beautiful!"

When the documentary director took the initiative to find Professor Lin Jindun, Lin Jindun still had many uncertainties in his heart. Because a series of films jointly produced by the News Bureau and the National Geographic Channel, "Blooming Real Taiwan" wanted to find out many Taiwan's characteristics, and through the lens of National Geographic, the whole world left a clear impression of Taiwan. Therefore, Lin Jindun had many doubts about whether his research could resonate with this topic, but under the director's lobbying, he decided to give it a try. In the first stage, a total of 88 films participated in the competition, and the competition was very fierce. After successfully passing the first level, the next two-minute film was to produce, and four of them were selected as the news bureau's praise. Among the twelve films, four of them were selected as the news bureau's praise.

The helper. Lin Jindun and the director decided to use creativity to subvert the traditional perspective to shoot cockroaches. They decided to close the action of cockroaches "washing the tentacles". I believe everyone is familiar with this action. You can often see cockroaches diligently twitching their hands and feet and washing their tentacles hard. "Is this like the protagonists touching their tentacles in a Chinese drama or a song drama? How beautiful!" Lin Jindun further stated that cockroaches are actually clean insects, so they always wash their tentacles constantly. After the broadcast, the Asian director of National Geographic Channel even took the initiative to tell them: "I have been filming for so long, and I never knew that cockroaches are so beautiful!" So they successfully obtained sponsorship qualifications.

Balance the importance of reporting

Lin Jindun believes that the "secret of cockroaches" can stand out lies in the fact that their works successfully convey the virtue of "promoting human nature", which is also the purpose that National Geographic Channel has always adhered to. In addition to showing the intent of Taiwan's academic community in research, it also allows people all over the world to feel the importance of respecting all things on the earth. After obtaining sponsorship qualifications, Lin Jindun and his team staff started the business system and filming work. He admitted that the filming work at the beginning was not very smooth, and many works that were hard-working were returned by National Geographic Channel. The reason was that they ignored "balanced reporting" at the beginning, which happened to be the country.

The geography channel attaches most importance to, so Lin Jindun and the production team reconceived the direction of the film and found a well-known domestic "worm-eliminating expert" to discuss the opposite side with Lin Jindun in the film, allowing the audience to think about the same thing from two different positions. After the video was released, Lin Jindun received a warm response, and many media flocked to interview him. Lin Jindun asked the reporter who interviewed him to enter the laboratory in person and "contact" cockroaches. Lin Jindun believed that only by experiencing the feeling of experiencing the situation can we accurately report fair news, which is the same as doing experiments. When on the radio program, he also received enthusiastic resounding from many listeners, indicating that he agrees with his research.
