I am using TnG ewallet to transfer money to my Alipay app. the first step to do is to switch Alipay to china version instead of global version from the option menu and do passport verification. Then search for and activate merchant service(商家服务）.
After activate, then you can perform request money, put in the amount and save the QR code, then pay with TnG ewallet by scan photo from gallery.
I did get scammed around RM200 for Alipay reload service at the beginning and after that used to reload tru shopee seller, but the price is higher compare to the conversion rate.

At home page got 收钱，press it, it will show QR code, then there is 设置金额，enter the amount you want request, then it will show the amount under ur QR code, then save the image and load to TnG, can try small small amount first for first time.

Nope, mine will show confirm payment page after scan QR code, then payment page will show powered by Alipay at the bottom.

Using 3rd party reload or purchase they charge high rate at >RM0.7x/1yuan, TnG rate at ~0.65/1yuan.

I use my courier warehouse address

verification only need passport. then refer my post above, see can or not

Your steps are correct, but I don't know what the issue if it failed, if went blank maybe TnG issue, it's not loading.
