What is the general tour to Korea duty-free cosmetics store, and the flight from Ningbo to Jeju Island?

Where are you going in Korea? I have just been to Jeju Island before. It is cost-effective to buy Korean cosmetics in duty-free shops, but some brands are bundled. Everything is sold in the form of 50 yuan, so it's best to find a partner, which is very cost-effective. There is no charge for buying things in duty-free shops. If you buy them in dollars, it is effective in cash. It's more cost-effective if you swipe your card. There is a handling fee for visas. Korean ginseng can buy some appropriately. If you join a group, a tour guide or something will take you to their designated store, which is generally more expensive, but the quality is guaranteed. You don't have to pay tax on the duty-free goods you bought in Korea when you return home.
