For me, the must-have apps on my phone are WeChat and Tiktok. WeChat is the largest Chinese social platform, and Tiktok is the most popular short video app nowdays. In my opinion, WeChat is a super-app on which we are able to chat with others, view daily updates, read everyday news, pay online and so on. Almost half the time I spend on my mobile is focused on Wechat. Its design is clean, friendly and full-featured, even though that may sound conflicting it is true. true. There is another widely used social app called QQ in China also, which is also developed by Tencent. QQ remains very popular in the web internet age since 2000. Compared to WeChat, QQ is a bit complex and fancy, especially for the aged and undereducated population in the mobile internet era. Thanks to carrying on QQ's existing relationship chain resource, Wechat was able to rise rapidly in the competitive market. Nowdays, Chinese all over the world are connected by WeChat. Tiktok is also an interesting app. There are plenty of funny short videos created by personal media individuals, involving every perspective of the world. I like watching musical dancing, daily news, knowledge sharing clips, etc. The most significant mechanism is automated recommendation by which more and more videos are pushed onto users. After the app opened, a system recommended video will be shown on full screen, and I just need to slide up to watch the next one. I can double-click on the screen to like the video. For many users like me, it's a lazy way to kill time, but for some others, it may be boring and noisy. Tiktok is also a live streaming platform on which users can interact more instantly with the anchors. This also makes Tiktok a rising e-commerce platform.
