Restaurants and restaurants in Qingdao often offer free food to diners.

Restaurants and restaurants in Qingdao often offer free salad seaweed to diners, and the seasoning is often just right. I remember when I was in school, I once went to a small restaurant with my classmates to eat steak rice. His steak had already been eaten, but the salad kelp continued one dish after another. I also added free rice all the time, which made the owner’s face green.
Laminaria japonica is not actually native to China. It was introduced into China from Japan around 1930. Since the late 1950s, along with the southward migration and promotion of kelp culture, Chinese people have quickly become familiar with this kind of seafood. At present, China has become the most concentrated area of kelp culture in the world.
