It seems like you are asking if it’s possible to directly buy Ctrip (a Chinese travel booking platform) tickets and whether the scenic area allows third-party ticket sales. According to your conversation with the scenic area, they mentioned that they don’t authorize any third-party sellers to sell their tickets.
Based on this information, it appears that direct purchase of tickets from Ctrip is not possible or recommended. Instead, as you’ve discovered through communication with the scenic area, pre-booking and purchasing tickets are only available through official public numbers (公众号) on WeChat.
So, if you want to buy a ticket for this scenic area using Ctrip, it’s necessary to go through an authorized public number rather than directly purchasing from Ctrip.
