I finally received the invitation from Baidu Youa.

The feeling is that it's indeed the internal test, the wide screen makes me feel uncomfortable. I need to verify my ID card and also need the debit card number. I don't have them. There's nothing I can do. I'll try with my savings card. It will take 3-5 days to get the approval notice.

There's also a special HI配套 for Ya! Everyone can download it to check. I've put the specific screenshots in the post!
