D 1- Busan Longtoushan Park, seafood flea market D2 Busan-Jeju Yuntai, Dragon Head Rock, Tiandiyuan Waterfall, Magic Road, columnar junction D3 Jeju-Seoul Chengshan Sunrise Peak, (at its own expense: 38 observation deck+Imjin Pavilion+tunnel 380 yuan/person), 2002 World Cup football stadium D4 Seoul Cheongwadae Gyeongbokgung Palace (at its own expense: 550 yuan/person) Hehe. My suggestion is to buy some Korean cosmetics, such as LG, Lan Zhi and THEFACESHOP. They are all suitable for our Asian skin, and the price is better than that in China, and the quality is better. If you eat it, you can eat enough Korean specialties for the reunion dinner. To tell the truth, this is still a first-class dish in China. You can buy some pickled ginseng, which is more expensive. It is recommended not to buy it. South Korea's Dongdaemun, Nandaemun and Myeongdong are all good places for shopping. You can also buy some favorite gadgets and bargain.
