Is there any short-term travel insurance for flying from Shanghai to Chengdu for three days on the first day of New Year's Day?

First of all, these four days are tense, especially in Chengdu, where there is a lot of fog in January. It is possible that the plane will delay a lot of time, so time must be reserved. As for the temperature, it's a little higher than Shanghai. Generally, it is less than 10 degree during the day and less than 1-5 degree at night. The tourist attractions are much colder.

If there is no bullet train, it is recommended to fly. If there is no fog, you can get off the plane at noon and leave Shuangliu Airport. It is suggested to find Jinsha Site, Du Fu Caotang, Wuhou Temple, Jinli and business hotels near Wuhou Temple in the urban area. The next morning, I went to Xinnanmen Station, took a bus to Leshan to see the Giant Buddha, and took a bus to Emei Mountain in the afternoon to stay in a hot spring hotel and soak in hot springs. On the third day, I will take the cableway up and down the mountain to see the weather. If it's okay, I'll go down the mountain in the afternoon and go straight back to Chengdu in the evening. On the fourth day, take a taxi to the North Railway Station, take the express train to Qingcheng Mountain, return to Dujiangyan in the afternoon, and take the red-eye flight back to Shanghai in the evening.

The cost does not include air tickets, and per capita is within 1500.
