Fruit, it seems that Korea doesn't sell papaya and litchi. There is no watermelon as small as China.
There are no hawthorn, melon seeds with shells, small walnuts and paper walnuts in Korea. Hawaiian fruit.
Beef jerky is delicious in China, but not in Korea.
There is no coriander in Korea. I really like coriander, but it is not sold in Korea.
South Korea doesn't have as much food as China.
