As far as eating is concerned, according to one person, three meals in the morning, noon and evening don't cost 30 yuan. I mean to go to that fast food restaurant to eat fried rice and mixed rice or something. If you go to a small restaurant, a meal will cost about 70 to 100.
Eating some special dishes will not exceed 200.
As for traveling to the ancient town, our rule here is that locals don't pay, but people from other places get a ticket, which seems to be 25 yuan.
Then you do your own shopping and go to the supermarket to buy clothes or something.
