If you want to go to the Western Union, just tell your friends your name. When the time comes, he will remit money to you and generate a monitoring number. You can use the monitoring number to go to the outlets opened by Western Union (usually opened by Agricultural Bank of China or postal service) and fill out the form with your ID card to collect it. It is best to know the remittance amount and the name of the remitter. It takes about 15 minutes for Western Union to arrive. But there is a time difference between America and us.
Pay attention and tell your friends which is the last name and which is the first name.
