The Zhongzhi Mountain of Lingxiu Junyi, the wetland of Wuxing Lake with beautiful scenery, the Qinshui River with flowing streams, and Yongji in the bend of the Yellow River are bred by the rich environment of the earth and the unique environment. Spanish experts in the asparagus consumption kingdom call it “the best place to grow asparagus”. Yongji Asparagus's aura of heaven and earth, the essence of all things, creates an incomparable intrinsic quality such as white color, thin skin, crispy and delicate meat.

Yongji was called "Puchong" in ancient times and was passed down as a capital. It is located at the southwestern end of Shanxi Province, in the southwest corner of Yuncheng Basin. It is located in the center of the “Huanghe Golden Triangle” area of ​​Jin, Qin and Henan. It is the southern gate of Shanxi Province. The geographical coordinates are 110°15′00′′～110°45′33′′ east longitude and North latitude 34°44′50′′～35°04′50′′. Yongji has a superior ecological environment and is a star city in the middle and lower reaches of the Yellow River. There are "China's Excellent Tourism City", "China's Charismatic City", "China's Couplet Culture City", "one of the 66 major tourist and cultural counties to be visited in a lifetime" and other honorary titles. Yongji's tourism resources are very rich, and cultural sites and treasure temples are famous. There are more than 140 places in celebrities' hometowns and mountains and rivers. One of the four famous buildings in ancient China, Qiquelou, the story of the West Chamber, the Pudong Temple, the Tang Kaiyuan Iron Bull, the National Scenic Area Wu Laofeng, the beautiful lady Yang Guifei’s hometown, etc. It has a long-standing reputation in ancient and modern China and abroad. Yongji City is a temperate continental climate with four distinct seasons and abundant light and heat resources. The Yellow River, the Lishui River and the Bend River form a valley plain. The soil is loose, fertile, breathable, and rich in organic matter. It provides unique conditions for the cultivation of asparagus, resulting in the color of white, thin, crisp and fleshy. Exquisite and incomparable intrinsic quality, favored by the international market. At the end of the 20th century, the United States and the Netherlands summarized the history of asparagus production in the world for hundreds of years, and proposed the allocation of agricultural resources for asparagus production: the lower the latitude, the higher the output of asparagus, the higher the latitude, the better the quality of asparagus; the relatively dry climate The asparagus in the region is lighter than the asparagus in the humid climate; from the dual factors of yield and quality, between 25 and 40 degrees between the north and the south, relative to the dry climate, it is the best growth zone for asparagus on the earth. . Yongji is the largest asparagus production base in the country. It has a planting area of ​​80,000 mu, a harvesting area of ​​60,000 mu and a total output of 32,000 tons. It is mainly concentrated in the Yellow River beaches such as Puzhou, Literature, Handan and Hanyang. Asparagus, also known as stone cypress, is a high-grade vegetable with a variety of nutrients. It is known as one of the world's top ten famous vegetables. The asparagus produced has two kinds of green bamboo shoots and white bamboo shoots. The white bamboo shoots are white, bright and spotless. . The green bamboo shoots are thick, the strips are straight, the taste is refreshing, the crispness is crisp, the flavor is unique, and the nutrition is rich. Especially the asparagus has a great inhibitory effect on the canceration of human cells, and it is the most effective anti-cancer health food in the world. First, the products are processed by local asparagus processing enterprises and exported to European countries such as the Netherlands and Spain.
