Again, for alipay, it was as simple as testing things out with y10 (round trip transaction) to make sure it worked. Then we followed up with 1000.

With WeChat, iirc he did all of verification steps except for the Chinese bank account and then contacted customer service (I don't know if he called or used the in app bot) to get an exception.

He would have survived without WeChat pay, but he was glad he put in the effort to get it working because it comes in handy in group settings.
