Originally, when everyone saw these funny and cute animated pictures, they just found it interesting and did not think about how useful they were in yy. But after Li Mu introduced it, they realized that this animated pictures were actually a new way of chatting that could replace text.

In the past, emoji expressions were only used as a text assistant for chatting, just like salt put into a dish, which can enhance the taste of the dish, but they cannot be eaten alone as a dish.

Now, the panda bear gif expression made by Li Mu uses exaggerated and funny actions and text, and can completely replace text in many situations. Moreover, everyone feels that this way of chatting is really too interesting, far beyond text chat.

Suddenly, the atmosphere in the entire conference room became enthusiastic, and everyone was excited because they saw a new way of presenting online chat, a brand new and interesting way of presenting.

Fang Xudong finally understood what Li Mu was going to do. Looking at these expressions, he couldn't help but shake his head and sighed: "Mr. Li, I thought I wanted to make a function of sending gifs to the other party in real time and allowing the other party to preview directly in the dialog box, just like file transfer. I didn't expect you to use it to subvert the traditional way of online chat..."

Li Mu smiled slightly and said, "Gif expression is a new direction we will focus on next. If we look at the problem from this level, technology is actually serving the content."

Fang Xudong asked curiously: "Mr. Li, since we have created this chat mode, under normal circumstances, should we encourage users to create their own content so that the GIF animation expressions can continue to increase? Why do we need to upload users and block the added functions?"

Li Mu said: "You are right. Normally, after you have developed your functions, I should not upload the user independently and close the entrance to add animations, but I had four considerations in the early stage:

First, if the child is still young and just learns to study, don’t take him to a bookstore or library. If there are too many books, he can’t pick it, and it’s easy to choose the wrong introductory reading materials;

Second, all parents will impose their own views and cognition on their children. Therefore, when the children first learn to read, what they see is determined by the parents based on their preferences. Only in this way can they ensure that the children do not have too many deviations;

Third, you should know the difference between built-in content and customized content. For example, our 20 gif pictures are built into yy. Assuming that all users have updated the new version of yy, then when all users send emoticons, we don’t need to really post emoticons. What we send at the data transmission level is actually a string of character instructions;

For example, the string of the first gif is bq0001. Then when the user sends the first image to another user, as long as we send the command bq0001 to the other party, the other party's yy will directly retrieve the image from the local area to display it. For us, the 1mb image may be reduced to 10 bytes, which reduces the bandwidth usage by how many times?"

Fang Xudong blurted out: "1mb is equal to 1024kb, 1kb=1024byte. If it is reduced from 1mb to 10 bytes, the bandwidth usage should be reduced by about 100,000 times."

Li Mu nodded and said, "Yes, the difference between 1mb and 1byte alone is not that big in absolute value, but think about it, our current more than 600 million users basically account for more than 90% of the global number of netizens. If these 600 million users send an 1mb animation expression every day on average, how much will it take for our bandwidth?"

As he said that, Li Mu said: "If we now open users to create gifs and send them, then these unofficial built-in gifs cannot be transmitted with short character instructions. If all kinds of custom gifs are popular among users around the world, it will take up a lot of bandwidth. Therefore, we don't need to let them enjoy themselves yet, so we should give priority to everyone."

Fang Xudong asked again: "Mr. Li, what is the fourth consideration?"

Li Mu smiled and said, "The fourth one is the private product I want to carry around the world. I want to kill the function of adding animations to the user, and then put the panda bear expressions inside for them to use, so that all foreigners know about panda bears, let them know that pandas are specialty products of China, let them like or like pandas more, let them want to come to China to see pandas, and let them choose the panda travel special product where we go to Taobao."

Speaking of this, Li Mu was a little excited. He stood up and asked with a smile: "Think about Australia, what is the first animal you think of?"

"Kangaroo!" Everyone spoke in unison.

Li Mu nodded and smiled, "Think about it, kangaroos are so ugly, and they are big and fierce, and they are not cute at all. Every year in Australia, people are beaten to death by kangaroos. This is not what I said, this is the official data. But even so, a large number of tourists flock to Australia to see it every year. In comparison, our national treasure panda can be said to be one of the cutest animals. It is no problem to see one of them. So why can't we develop panda tourism?"

The core layer present finally fully understood Li Mu's intention. Fang Xudong said excitedly: "Mr. Li, let's build these emoticons into the new version of yy today!"

Li Mu nodded and said, "This batch is listed as "Panda Bear Issue I", and then reminded users that the second issue "Panda Bear" is being produced, so they can pay close attention."

As he said that, he instructed Fang Xudong: "The first emoticon package will be updated with our new version of yy, and the data will be directly put into the installation package. However, if there are new emoticon packages in the future, users will directly download the cache emoticon package data in yy."

For a software product, launching a new sectional function is a relatively large upgrade, and a new version must be downloaded and installed again.

It’s like the early WeChat Moments could not be published. Later, a function of shooting ten-second videos was added to publish Moments, which required version upgrades;

Later, WeChat further upgraded the video function. Users can choose a video from their album and cut it for ten seconds to post it on WeChat Moments. This also requires version upgrades;

It’s like yy now launches the function of dynamic emoticons, which must be upgraded through the version to achieve. However, in the future, new emoticons are released, only downloading and cached within the emoticons function.

In addition to custom emoticons on WeChat, there are also some official theme emoticon packages. All of these emoticons need to be downloaded. In the future, yy's gif emoticon update will also adopt this mode. If users are interested, they will download it themselves. After downloading, they will appear in their emoticon list. When sent to the other party, they will not occupy bandwidth.

Fang Xudong thought for a while and said, "Mr. Li, the first emoticon package is built into the installation package, which is easy to deal with. However, if a new emoticon package is launched and the publisher downloads the emoticon package but the receiving user does not download it, then although we save a batch of incoming bandwidth, we will still be occupied with a batch of outgoing bandwidth."

User a caches the second period's expression and sends one of them to user b. The logic of this data direction is that user a first passes the file to yy's server, and then sends it to user b.

Since user a has been cached, he only needs to send a character instruction to the server, and the server can know what he wants to send. If b also caches the second period's expression, the server only needs to send the character instruction to b;

However, if user b happens to have no cache, then the instruction issuance cannot call up the image locally in b, so the image can only be transmitted to b.

Li Mu thought about it slightly and said to Fang Xudong: "You add a set of code to the new version of yy. We can actively choose whether to automatically cache any emoticon packages released by the official."

Fang Xudong asked in surprise: "Does you mean automatic cache to inform the user or?"

"Of course I won't tell you." Li Mu said seriously: "Just just cache silently."

"Silent cache?" Fang Xudong asked with some concern: "If it is discovered by peers or users, will we protest that we force users to cache emoticon data without the user's permission?"

Li Mu waved his hand: "This is not a snooping into user privacy, nor does it bring any security risks to users. It is just a normal cache of the software's own data. If it is exposed, we can say that this is to improve the user experience, because if the user does not cache the animation, he will also need to occupy the Internet speed when receiving it. If the Internet speed happens to be not good, the loading speed may take a long time, which will affect the user experience even more."

In fact, Li Mu knows better than anyone else that there is no software in the world that is not a rogue.

Rogue software does not have to be 3721, or it is so obvious to some degree. For example, when Microsoft strongly promoted Windows 10, it became a rogue software itself.

In the era of mobile Internet, many software will have high-definition open-screen advertisements, and some will even video advertisements. These software will symbolically add a reminder like "Advertising is cached under wifi", but if you don't even have wifi, it won't put advertisements? If it doesn't exist, it will still automatically help you cache various advertisements, which will annoy you;

Take WeChat for example, Guangdiantong advertisements often appear in the circle of friends, which also requires data and traffic. Why consume users' traffic and place advertisements in the user's circle of friends?

If you browse ten Weibo posts, half of them are advertisements, let alone them. What’s more hateful is that half of the ten Weibo comments are advertisements. In order to increase the number of advertisements, the platform has already used all kinds of things.

Not to mention that many software are secretly recording user cookies, browsing history, address books, photo albums and other private information.
