The construction market is divided into outside and inside. It's a seafood wholesale market, with fresh wholesale, restaurants, shopping streets, and, most importantly, a popular sushi street. It feels like a tourist attraction. The market has been busy since 4 o'clock in the morning. There are fresh salmon to be auctioned, but if you wait in line to get them, you won't be late. A lot of people go for sushi. They almost have to wait in line for more than an hour. If you like sushi, you must go. Ordinary order is set meal, 170 yuan a set meal. There are so many people coming here to eat that almost every family is full before the meal is served. Famous restaurants are still in long queues around 1:00 p.m. The road of each passage in the market is very narrow and crowded, and there are many queues of people. Some places will be blocked. If you don't go to famous restaurants, you may not feel much worse if you enter any of them. After all, they are fresh goods. In addition, there are many shops selling seafood specialties in Zhengdi market. They are well packaged, moderately priced and tasteless. It is also good to pack some seafood as gifts for friends. It should be noted that most of these stores do not pay credit cards, only cash.
