My understanding of both Alipay and Weixin is that when you link a bank account your name on the bank account must match with absolute precision your name on the payment app, which is normally your name as shown on your passport.
This is not the case with Alipay. I have two credit cards linked to it with names in opposite orders (Last First Middle and First Middle Last). WeChat on the other hand requires (Last First Middle). You may succeed in adding a card with (First Middle Last) to WeChat but it will never pass real-name verification and you'll forever be prompted to upload your passport details (sometimes once for every transaction).
