Not Weibo (Weibo is more like Facebook). He says he wants to be like WeChat. As someone who lives in China and uses WeChat for everything the best way I can describe it is it's WhatsApp with an instagram like "moments" section and tiktok like "channels" section. But where it's different is the QR payment system which you can use to pay for everything and other useful things built in like Didi (essentially uber) and things like train booking, ways to pay your phone bill, pay utilities and lots more which I haven't discovered. The one thing it doesn't have is the Amazon like function which you mentioned.
