Is Qingdao Light Metal Co., Ltd. a subsidiary of China Aluminum Industry?

There is no guarantee that you are not a liar, because the film will be disguised by a named company, and some will show you the website, but it is not their company at all.

You can search its number online.

If it is indeed the number of that company, call that company to confirm it.

Although Qingdao is not far from Yantai, it can't be careless!

It's safer to find someone to go with, or find a classmate who is kind.
