PS; I don't know where your home is. If your home is far away (Gansu, Guizhou, etc., the ticket source is relatively tight in Spring Festival travel rush), I hope you can also book tickets outside the school (that is, near the Oriental outlet of the off-campus Internet cafe or Luchaogang Railway Station), because the school may not be able to book tickets. We had many classmates last year, and the school didn't buy tickets. Finally, I queued up to buy it myself, which gave me an extra guarantee. Even if you buy two, you can finally sell one!
