Air ticket 1000, round trip 2000.
If you stay in Lijiang for 5 nights, one night 100, the total accommodation is 500.
Have a meal, one meal 15 yuan, 6 days *3 meals * 15 yuan =270.
The above basically adds up: 2770 yuan.
Others need to add play fees and shopping.
Shopping is generally controlled by yourself, generally not exceeding 1000.
The tour fee is mainly to go to a scenic spot for a group reunion, which requires money. You should be able to visit many places in 6 days and 2000 days.
So the total is 2770+ 1000+2000=5770 yuan.
The above calculation is relatively loose. In fact, according to your own situation, you should be able to save a lot, and around 3500 should be enough.
