There is still time for train fares from Huizhou, Guangdong to Chengdu, Sichuan. How long in advance should I make a reservation ... What's the ticket price from Chengdu to Guangzhou?

There is only one train, T 128, and the full price is 288. I got on the bus in Huizhou at noon 12, and it opened in Dongguan. Run for 30 hours and arrive at Chengdu Railway Station at 6 pm the next day! Air conditioning is express delivery, but this car is generally hot, and there are not many seats in it! You can book tickets 10 days in advance! The full price of the plane from Guangzhou to Chengdu is 1400, but you should be able to buy a 40% discount ticket recently, plus the airport construction fee and fuel fee, which is about 800 yuan! For details, you can chat with Q, 1 134867895. I am from Sichuan and studying in Huizhou!
