After eating melons for half a day, I tried donating and successfully solved my doubts, haha.

The success page is shown in Figure 1. The phone number is like this. I tried it, and before payment, I filled in + in front of the phone number. After payment, it retained the +; before payment, I didn't fill in + and it didn't show after payment either. Sometimes there is + and sometimes there isn't. I don't know what's going on.

As shown in Figure 2, P should be less noticeable to some people. For example, I made it 88888. As shown in Figure 3 🤣

You will receive an email after making a donation, as shown in Figure 4.

The above content is purely for entertainment. Just take a look and have fun, haha.
