When is the right time to start, please recommend the travel route!

Where should I go? What do you recommend? <br/>Personally, I plan to go to Chiang Mai, Thailand at the end of November, there will be Loy Krathong Festival

I really think now is a good time,

I really think now is a good time, no matter where you go, it is neither too hot nor too cold. Western Sichuan, Yunnan, Guizhou, and Yunnan-Guizhou Plateau are all picturesque, with good weather and safe road conditions, and avoid the Golden Week!
