The drug approval number is: "National Medicine Zhunzi H (or Z.S.J.B.F)+8 digits", which means the drug approved for production and marketing by the State Administration of Pharmaceutical Products. The letter H stands for chemicals, Z stands for proprietary Chinese medicines, S stands for biological products, J stands for domestic packaging of imported drugs, B stands for adjuvant drugs, and F stands for pharmaceutical excipients. If there is no "national medicine quasi-word" on the package, it is definitely not a drug.

On the packaging of health care products, you can definitely see the approval number of the State Drug Administration: the word G(J)+8 is a number, and the letter G stands for domestic J stands for import. Or the approval number of the Ministry of Health: Wei Shi Jian Zi (Wei Shi Jin Jian Zi) +8 digits. It is also stipulated that the package or label must be marked with a special logo for health care products: "Police Mobile Force", with a pattern similar to that of the police mobile force, with the words "health food" below and the approval number "health food" below. Those who don't have the approval number of the police mobile force and health food are fake health care products.
