Let me add something for you. 1200 is definitely enough for two people to play in Changsha for about three days. Take 1 12 huang xing road pedestrian street and get off at Simenkou Station. Anyway, there are more people getting off at that station (that is, there are yellow ones).
Why don't you take a taxi? You can stay next to the pedestrian street for 7 days and check online for 7 days. It's 5 minutes from the pedestrian street. You get off at the railway station, take a taxi in the square, and say that you will go to huang xing road pedestrian street for 7 days (it should not exceed 20 yuan. I'm telling you, go straight by car, take wuyi avenue and cross two blocks. There are many people there anyway. )
Just play on the pedestrian street. Anyway, there are more things to go, and it is more prosperous! For nightlife, you can go to the bar on Jiefang West Road, which is a famous bar and street in China. It's high there! For example, you can also go to the Fire Palace in Changsha to eat Changsha's unique snacks. You can also go to Yuelu Academy in Hexi. Of course, Hunan History Museum is also worth a visit to learn about Chu culture, and there are no admission fees. What is worth seeing is the thousand-year-old remains of the Queen of the Western Han Dynasty, which is unique in China. This is really a miracle and an eye-opener, and it is a national first-class cultural relic.
I have calculated the air tickets for you: round trip for two people 170 yuan, seven-day drive in Changsha 128 yuan (or take a taxi to 50 yuan), and 384 yuan for three nights. Eat in 200 yuan (there are many national chain stores on the pedestrian street, so you can eat whatever you want). Then go shopping, I don't know, have some snacks (100 yuan)
170+384+ 150+200, and the rest can be bought.
