Today, I received a phone call from Tianjin Yipin Cultural Center, saying that I could use this short message to go to the third floor of Tianjin Heping District International Building.

Dear Baidu bloggers, first of all, I can be sure that this activity does exist and the prizes given do exist. You can get one if you like or it's convenient. But this is just a gift commemorative coin. It can't be the high-content silver product you imagined. I have received it. It's exquisite. It should be made of silver. Go there if you are interested.
