Before I came to Sanya, I would visit the first market every time. Although the price is not too cheap, there are many kinds of seafood here, so what I want to eat can be bought all at once. Come to Sanya this time, and continue to visit the market with children. Unexpectedly, more than two years have not come, the changes around the market are still quite big. In the past, the market was full of stalls and fruit stalls, all kinds of disorderly, now come along, a lot of clean on the way, no salesman to pass you business cards, the whole shopping environment is much more comfortable. Children in the market see a lot of seafood, many still can not name, but now in every seafood stall they will put a label on the name and price of seafood, so that even if they do not know what, they can read the label text themselves. It takes more than an hour to go around the market. For children, it also increases a lot of knowledge.
