Name Typo error found on E booking

Based on the real name policy, the name have to be the same with your travel document. This also depends on individual as well. If some stations or staff are very strict with the name, you may fail to exchange the paper ticket. If possible, maybe you can try to exchange it days in advance. If you failed, you can still try to cancel it and buy a new one. If you do not want to take a risk, you can buy the new one now.
