How did the Chinese herbal pieces that Angelica often put in stew come from?

As far as I know, the famous Danggui decoction pieces are Minxian Danggui decoction pieces in Gansu Province, which are the characteristics of local traditional agricultural heritage. Minxian county is characterized by rolling mountains, criss-crossing gullies, cold and humid climate, and most cultivated land is mountainous and semi-mountainous areas with good vegetation. This special geographical and climatic condition is especially suitable for the growth of Angelica sinensis.

Farmers rotate Angelica sinensis with wheat, potato, broad bean, rape and other crops, adjust temperature, moisture, light, soil, fertility and other factors, and adopt traditional methods such as applying more organic fertilizer, digging deep into the soil, standing in the sun and disinfecting the soil to reduce pests and diseases and ensure high yield.

Minxian established a nature reserve for wild resources of Angelica sinensis, protected its germplasm resources, and bred varieties of Angelica sinensis with better characters and higher yield. At present, there are three varieties of angelica suitable for planting in Min County, namely "Min Gui" 1, 2 and 3.

One acre of medicinal materials, ten acres of fields. The development of Angelica sinensis industry has greatly increased the per capita income of Min County, and also protected the ecological environment of the heritage site, which made the local people bid farewell to the old road of deforestation and ecological destruction, and the ecosystem of the heritage site was restored.

Minxian has been processing Angelica sinensis by traditional methods. Smoke with firewood to block the pores on the epidermis of Angelica sinensis and prevent the loss of volatile oil from Angelica sinensis. Then the medicinal properties of Angelica sinensis were ensured by insecticidal drying treatment, which was beneficial to the preservation of Angelica sinensis.

The local diet in Min County is mostly related to Angelica sinensis, including seasoning Angelica sinensis, medicated Angelica sinensis, stewed Angelica sinensis and drinks Angelica sinensis. Well-known specialty foods include angelica sheep, angelica chicken, angelica wine, angelica sugar, angelica vinegar and angelica biscuits.

In midsummer, Angelica sinensis in Min County is a natural landscape, especially the 10,000-mu Angelica Corridor in Xichuan, which is the most beautiful and intoxicating. The bonsai of Angelica sinensis in Minxian County is a perfect combination of nature and art, with huge taproots, stout branches and diverse shapes. After cutting and shaping, it looks like a dragon and a crouching tiger, which embodies the wisdom of the people in the heritage site.

Since 2006, Minxian government has continuously held "China Danggui Festival" and other major events to strengthen the brand building of Danggui and inherit and carry forward Danggui culture.
