How do the residents of those small islands in China live?

The favorite place to go in summer is the seaside. Take a bath, barbecue and drink beer in the sea. Throw a watermelon into the sea and refrigerate it for a while, then blow a small sea breeze. I seldom go to the seaside in winter. Is the sea breeze too strong? Every year the Dragon King's birthday is very lively. Some boatmen set off more firecrackers than during the Spring Festival. Fishermen are willing to give the Dragon King something nice for his birthday. It seems that the people on the island are very poor, and there seems to be nothing good about food, clothing, housing and transportation, but there are many rich people and fishermen are also very rich. Perhaps the habit formed by several generations is very simple, and it is very tiring to keep a boat, and there is basically no time to enjoy life.
