Don't follow the external market, there are few gaps, and the market is generally out of the day.

Reason: the outer plate is made of raw sugar, and Zhengzhou is made of white sugar. There is a difference between the two. China can basically be self-sufficient, and sometimes it has a slight surplus, so sugar is basically different from the external market. It is precisely because sugar does not look at the face of the outer plate that it has always been a deeply controlled variety. It is not uncommon for the market to rise and fall every day, and it is very difficult to operate in the short term, so it is often called "demon sugar" by the people.
