What does it mean for Meituan to buy medicine to supplement prescription information?

Prescription drugs must provide proof. Meituan buys medicines to supplement prescription information because it is an official rule that Meituan must provide proof when buying medicines and prescription drugs. Because prescription drugs are controlled by the state, the system will prompt you to issue a prescription drug certificate after the US Mission purchases the prescription drugs and places an order. If you don't have proof of prescription drugs, you can find the lost proof function, let the online consultation doctor issue a certificate, and then you can place an order successfully after reviewing the order.
