How much does it cost to travel from Suzhou to Korea?

I started from Xi 'an (the price of the travel agency should be similar). On July 5th last year, I went to Seoul and Jeju Island with a group, and it was only 3 180. And now that the Korean won has depreciated sharply, it should be cheaper and cheaper. Cosmetics are cheaper. Fruits for daily use are very expensive (one special orange in Jeju Island 1500 RMB 9 yuan, five peaches are discounted in 30 yuan), and the taste is average. You can try oranges. And scanned a lot of CDs. But still not satisfied. The tour time is limited and the food is average. I was mainly influenced by Korean stars and Korean dramas, and I met my wish after the college entrance examination. It is suggested that you turn at Mingdong instead of Dongdaemun.
