The hilly area around Wugen Mountain is the famous Guo Hua in chongzhou city. On the shallow mountain stretching for more than ten miles, sightseeing tours of flowers and fruits in spring and summer gradually took shape. The brown plum in Guo Hua, Chongzhou, originated in the United States. It is a kind of high-quality fruit with good color, fragrance and taste, and has the reputation of "plum king". Because of its remarkable economic benefits and good market prospects, relevant experts have designated American Brownlee as the first choice for Sichuan to implement the strategy of developing the western region and adjust the fruit structure. Up to now, more than 30 varieties of 1 1000 mu of brown plum have been planted in chongzhou city, with an annual output of nearly 1000 tons. In 2002, chongzhou city was named as the only "Hometown of Brown Plums in China" by the Ministry of Agriculture. Chongzhou seized this opportunity and started to build the Brown Plum Fruit Picking Festival in 2004. In recent years, with the success of the picking festival, thousands of citizens have opened their hearts and filled their stomachs with fresh fruits, and the villagers in Huaguoshan have quietly earned a lot of money. When the first Palm Plum Picking Festival was held in 2004, more than 654.38 million people from all walks of life were welcomed, and the price of plums was per kilogram 14 yuan to 16 yuan.
