To buy saffron in Lanzhou, I suggest you go to a local drugstore or a Chinese time-honored drugstore, such as Tongrentang. The price of saffron is 70 ~ 100 yuan per gram. The situation varies slightly from place to place. Although the price is higher, it can be guaranteed to be genuine. Other small pharmacies have no saffron or no real saffron. Many small pharmacies sell saffron as saffron, and some sell it directly to you. If you are familiar with online shopping, I recommend you to look at the "Saffron Beauty Health House" on Taobao. They have 8 years of experience in the saffron industry and have their own saffron planting base. The saffron they sell is of high quality and low price. Every gram of Iranian imported super saffron 25 yuan, domestic super saffron 35 yuan. You can go and have a look.
