Please recommend some interesting places to travel in Changsha.

A one-day trip to Changsha is enough. Conventional attractions: Orange Island, Yuelu Mountain, Tianxin Pavilion, Window of the World, etc. Nightlife as long as it is a bar on Jiefang West Road. The most cost-effective hotel is of course 7 days or something. Snacks are concentrated in Pozi Street near the pedestrian street in Tianxin District, all of which are century-old shops.

Zhangjiajie, the most worthwhile place to visit in Hunan, lasts for almost 7 days, and 5,000 yuan is basically enough.
