First of all, I want to introduce the economic situation of this country. It is one of the least developed countries and poor countries in the world. 8% of the population is engaged in agriculture, with a GDP of about $835. Ok, let's start with the exchange of two currencies. At present, 1 yuan is equivalent to 15.6 Nepalese rupees. In Nepal, you can find a shop opened by local China people to exchange money.
In Nepal, a big meal like a barbecue hot pot costs about 1,-2,5 rupees, and an ordinary plate of steamed buns costs 6 rupees, so the food you can get for one yuan, that is, one or two steamed buns, is not much different from the price of buying steamed buns in China!
But in China, you can hardly buy snacks for one yuan, but in Nepal, you can buy simple snacks, such as fried meatballs and rice cakes, but forget about meat dishes. The possibility is basically out of the question. Nepal is rich in citrus and apples, but the price is not cheap. Apples cost rmb1 yuan a catty, bananas may be relatively cheaper, and you should be able to buy two for one dollar.
Handicrafts are relatively cheap in Nepal, because the local labor costs are relatively low, so one dollar can buy many local handmade gadgets. The local handmade wool scarf is only 6-8 rupees, so it is also a good choice to buy one with some money! Anyway, compared with China, the prices there are still relatively cheap, so you can eat, drink and be merry there. But I don't think there seems to be any interesting places in Nepal, because the country is too underdeveloped, and it is better to visit the great rivers and mountains of the motherland, or it is not bad to visit some developed countries!
