The entire island of Jeju is a treasure.
There is no place which is not beautiful.
The population of Jeju-do is about 500,000.
Without specific resources, most people live working in agriculture and tourism, and mandarin is well-known as one of Korean specialties.
The number of annual tourists to Jeju already exceeded 7 million.
Therefore, there are more people who are engaged in tourism than any other places in the country, and it is not too much to say that at least one family member is engaged in tourism.
