Does Ningxia Helan greenhouse vegetable base make money? Is it a pyramid scheme?

It is not a pyramid scheme, but a collective planning project of the local government. The land of local farmers was bought out by the government, which built vegetable greenhouses and sold them to farmers to grow vegetables. Whether you can make money depends on what kind of vegetables you grow. Everyone knows the relationship between supply and demand in the market. Supply exceeds demand, so naturally it can't sell well. But on the whole, greenhouses make money in one year, but earn more and earn less.
