1️⃣ My aunt’s cousin is in Shenzhen and she is doing payments on Web2. It’s difficult in the early stage and she gets rich later. 2️⃣ When I sent him a Yantai Apple last year, he said that he, as a fellow traveler, went to Hong Kong to make a "U card". 3️⃣I asked, why don’t you do it? He said, “there is still a risk” and he said he didn’t want to fight so hard. 4️⃣ So, I think the "U card" is very mysterious. I think I should open one, use it, and experience it, and there is no prejudice.
