Can I buy anything good when I travel to Korea125,000 won?

I am in Nanjing, China Eastern Airlines has a round trip of 3200 and a visa of 600 (please ask a friend to issue me a visa from Shanghai Travel Agency). I live at my friend's house. First I went to Ulsan 330 (not fun), and then I took the high-speed train to Seoul (270). After shopping for seven days, it cost about 3000 yuan. Food is expensive, but cosmetics are cheap, and clothes in season are also cheap. I'm talking about RMB! For example, a cold noodle 40 yuan, Coke 8 yuan, orange juice 15 yuan, rarely, subway 9 yuan (these are all Korean won with two zeros removed, which are generally counted), bus around 6 yuan, Nanshan cable car 50 yuan, the cheapest clothes are almost 50 yuan, ice cream 25 yuan, and a pineapple 10 yuan. Most importantly, Korean shopping bags are all. Of course it's expensive. Small shops don't bargain. In China, 10 yuan costs 50- 100 yuan. Like earrings. What else is there? I won't know until I continue my trip tomorrow!
