I was told that I had to go to Shanghai with a letter of introduction from the Organization, which is the case for the whole country. Isn't it a decoration?
If I am an employer in Tibet and I want to go to Shanghai to verify the applicant's certificate, it's really funny. It seems that if a friend fails,Draw one by yourselfIt can be used. The phone number on the certificate is blank, and the office of CET4 and cet6 has to be queried.
