This time, I am going to take my family to visit the ancient battlefields of Tongshan Yinshui Cave and Chibi Three Kingdoms. Because I booked tickets for Yinshui Cave attractions on October 1, the Internet reflected that online customization was not accepted on the 7th of the National Day, and I did not book it. On the evening of the 2nd, I logged in to Trip.com again and successfully booked 5 tickets for the ancient battlefield of Chibi (because I arrived at the attraction on the 3rd and found half tickets for students, so I actually picked up 2 tickets), but the tickets for the hidden water cave attractions must be one day in advance and before 16:00, so the reservation was not successful.
