Wenjiang, located in the hinterland of Chengdu Plain, is 10 kilometers away from Chengdu, the largest city in the southwest. It has a pleasant climate, flat geothermal area, fertile land, mild climate throughout the year, and small temperature difference. It is the core area of the national ecological zone. At present, the bonsai planting area in Wenjiang District is more than 10,000 mu, mainly distributed in Yushi, Shouan and other towns. The main varieties are black persimmon, plum blossom, crabapple, Podocarpus, crape myrtle, ginkgo, June snow, etc. Bonsai products are sold well throughout the country and exported to South Korea, Japan, Singapore, Hong Kong, Taiwan and other countries and regions. Wenjiang's Sichuan bonsai coiling technology originated in the late Qing Dynasty. In the late Qing Dynasty, Baihua Village, Shouan Town, had formed western Sichuan flower and tree bonsai, which is one of the birthplaces of western Sichuan bonsai. The history of the Chen family, represented by "Western Sichuan Flower King" Chen Kaiqin, planting flowers and trees can be traced back to the Qing Dynasty, and it has a history of more than 150 years. Chen Kaiqin is one of the top ten bonsai masters in China. He is proficient in the creation of Sichuan bonsai and has trained many outstanding disciples in the bonsai and gardening circles, promoting Sichuan bonsai. His skills are superb, and he has integrated the production, cultivation, and modeling of flowers in western Sichuan with the gardens of the Qing Dynasty, and he enjoys a great reputation. Since the 1970s, while Wenjiang western Sichuan flower and tree bonsai has been growing and developing in Wenjiang for many years, it has actively led the surrounding farmers to engage in bonsai flower seedling planting, Sichuan bonsai production and flower and tree circulation. The flower and tree varieties include Podocarpus, Malus, Osmanthus, Magnolia, Crape Myrtle, Ginkgo, Golden Ball Stump, etc. Driven by a large number of skilled bonsai art masters such as Chen Kaiqin, Ye Ruijin, Li Mingfu, and Wang Yongdi, Wenjiang bonsai has formed a large number of bonsai coiling professional teams and bonsai professional villages such as Shou'an Baihua, Huangnian Village, and Yushi Jinma Village. At present, Wenjiang District is planning to build a 10,000-acre Sichuan bonsai base. After completion, the annual output of various bonsai will reach more than 1 million pots, and the annual sales will reach more than 100 million yuan, which will have a positive impact on the development of Wenjiang's flower industry. Sichuan bonsai has unique skills and methods for stump modeling, rock bonsai modeling, and tree-stone combination bonsai modeling. Stump modeling can be divided into multi-trunk style, one-tree multi-trunk style, oblique floating style, supine style, river-crossing pine style, large cliff style, small cliff style, jungle style, and stone-attached style. In short, it is to artistically process and treat the stump according to its natural form to make it shine with spiritual brilliance. The modeling skills of rock bonsai pay more attention to the beauty of the contrast and unevenness of the scenery. Its methods include separation and combination, one-corner style, scattered point style, high and far style, flat and far style, deep and far style, and the law of the rise, development and transition of the mountain, emphasizing the beauty caused by vision. The modeling of tree and stone combination bonsai is mainly divided into dry style and water-dry style, and different artistic atmospheres are created according to different objects and environments. The modeling of water-land bonsai is more complex and varied, emphasizing the harmonious unity of the beauty of mountains and rivers. The Sichuan bonsai is a process from simple to complex and then from complex to simple. The former "simple" is simple, and the latter "simple" is concise. Like other bonsai schools, according to the modeling principle of "tree posture close to painting", there is the natural type first, and then by imitating the posture and changes of old trees, the technical rules of expressing this posture and change are constantly summarized. Through the creation and improvement of bonsai artists of all generations, it is finally summarized into the method of body type (respectively, the method of turning and turning, the method of connecting and turning, the method of rolling dragon holding the column, the method of three bends and nine inverted turns, the method of square turning, the method of old woman dressing, the method of straight body crowning, the method of large bend drooping branches and the method of clever borrowing) and style. Chen Sifu, a master of bonsai art, wrote in his monograph "Bonsai Stump Head and Banner Tie Technique": "If we talk about the regular flat skill-style stake heads, the main trunks in Chengdu and western Sichuan are bent and tilted downward, which is modeled after the low and old pines and cypresses that have been suppressed by snow for a long time in the high and cold areas of Mount Emei. After the snow melts, the treetops stand upright, and the branches turn from hanging to slightly tilted. Therefore, the regular type of flat branch stake heads, the branch plate gradually tilts downward and flat to the end of the plate, or the base of the skill plate tilts downward, and the plate is slightly tilted downward and flat." This shows that the regular type comes from life. But it is higher than life, it is an artistic summary and artistic processing of nature, and then, like the "rhythmization" of classical poetry, it makes it concentrate on displaying the basic principles of traditional aesthetics: symmetrical beauty, balanced beauty, rhythmic beauty, seeking change in unity, unity in change, lively and orderly, solemn and smart. "It breaks away from the blind control of natural phenomena over bonsai art, and controls its reflection object with clear rationality and abundant emotions. On the one hand, it reproduces nature, and on the other hand, it actively expresses people's aesthetic ideals of nature. In terms of artistic form, it uses strict rhythm as the basic structural principle. It is the 'metrical poem' in bonsai."
