Special circumstances. Ladies and gentlemen, there are special circumstances in the pen, I must come to Shanghai in a hurry two days ago, and I must rush back to Nanning tomorrow, and the train tickets have been bought. Two nights and one day of train, the time was spent on the train, and now there is no money to buy a sleeper, so I have to buy a hard seat, and I can't code words on the train, I'm sorry. The pen promises that after returning to Nanning, there will be a big outbreak to make up for the relatives.
