Some provinces, such as Hubei, stipulate that your products can be sold in the whole province if they bid and win the bid. If the bid fails, it cannot be sold in the whole province. But if you don't participate in the bidding of essential drugs, your products can still be purchased in big hospitals.

Some provinces also have regulations on the purchase amount of basic drugs in hospitals above the second and third levels.

Non-base drugs can enter private hospitals and clinics, but the price is not limited by the bidding price.
