One more thing, Tongrentang drugstore has a unified price throughout the country. If you buy gold plating, it should be 160 yuan, and if you buy gold plating, it should be 350 yuan. If the price is different from this, you should consider it.
It is worth noting that what I just said was the price bought by Tongrentang Pharmacy. If you buy the Angong Palace in Tongrentang in other pharmacies (such as Golden Elephant), it will definitely be lower than this price.
