"Changgou brand" grapes are delicious, and Jining people are well-known. It took Changgou Town nearly 26 years to build this famous brand. Changgou Town has unique conditions for growing grapes, fertile land, rich in organic matter and various trace elements needed for grape growth. The present Changgou Vineyard is located in the middle of the ancient canal. 1984, Jian Xu, the current president of Changgou Grape Association, introduced the Japanese variety Kyoho Grape from Laixi. From the first day of introduction, he led fruit farmers to explore the delayed grape picking technology. Due to reasonable fertilization, good pest control and long leaf duration, fresh and tender green leaves continuously transport nutrients to the fruit through photosynthesis, making the fruit large and transparent, with high sugar content and good taste. The fruit hung on the top of the branch for two months did not rot, and the picking was delayed for one month, avoiding the peak season of Dalu grape. During the peak period of Double Eleven and Mid-Autumn Festival every year, the sales of Changgou grapes end on Lunar New Year 10, and the net income per mu is around 3 yuan -4 yuan.

Successive party committees and governments in Changgou Town have given strong support to this advantageous industry in terms of policies, funds and technology. Hundreds of thousands of yuan have been invested to repair the vineyard road 10 km, erect high and low voltage lines 10000 m, dig drainage ditches for 5000 m, and drill wells 100 m, thus relieving the worries of the masses. The town government also used the Agricultural Broadcasting School and the Farmers' Cultural Science and Technology School to regularly invite fruit tree experts to the town to give lessons to fruit farmers, and married with Shandong Agricultural University and Zhengzhou Fruit Tree Research Institute of China Academy of Agricultural Sciences to establish grape demonstration bases and seedling breeding bases. More than ten varieties such as Meizhi, Ruby, Heiti and Hongti were introduced from Dazeshan, Qingdao. Fruit farmers are often organized to visit and study in grape producing areas to broaden their horizons and learn from each other's strengths. With the strong support and active guidance of the town Party committee and government, Changgou Town established the Grape Association, with Jian Xu, the king of grapes, as its president, and printed a membership card with photos for each member. The association has played a very good role in organizing the production management and sales of its members. They hold regular meetings to pass on information and exchange experiences. The association regularly tests and analyzes the nutrients in the land and formulates prescriptions for fruit farmers to fertilize according to the formula; At the critical moment of disease prevention, "consultation" for grape diseases and insect pests, find out the cause and prescribe the right medicine; When selling, members must obtain sales permission, and children will not be cheated. In order to improve the popularity of Changgou grapes and crack down on counterfeiting, the Changgou Town Government invested to register the trademark of "Changgou Brand" in the State Administration for Industry and Commerce, and made a lot of advertisements in newspapers, radio stations, television stations, the Internet and other media, which greatly improved the popularity of "Changgou Brand" grapes. The town government also uniformly printed packing boxes, made anti-counterfeiting signs, and actively matched the bridge and sold it to markets outside Jining.

Through the unremitting efforts of the town government and fruit farmers, Changgou Brand Grape Demonstration Park won the title of Grade 4 Orchard, and "Changgou Brand" grapes have successively obtained the pollution-free and organic food certification from the Ministry of Agriculture.
