Blank Daily Station

Lin Cheng found that there was one day missing from the calendar, but his colleagues insisted that he had been to the hospital; there was an extra pair of shoes with the same size at home; there were three rules written on the back of the visitor registration form - don't fill in the missing day, don't ask about things that others remember, and some places can only appear in other people's sentences. Some station names cannot be reported; if you register, you will get off, and there will be no return trip after getting off.
