You can stay in a motel in South Korea for 30,000-50,000 yuan a day. It is very comfortable and you don’t have to pay attention to what others do.
If you want to live in a high-end hotel, you can stay at the Mitsui Hotel for 120,000 a day. This is in Seoul.
It depends on what you like, no one is going to rip you off, it costs about 50-100 million per meal.
I can go with you if I have time, but I don't have time.
In fact, Korea is not a place for shopping, Hong Kong is.
