[Landmark Geography] Good water fertile soil, good fortune, new lotus root is mainly produced in Wanqingsha Town, Nansha District. Wanqingsha Town is still a sea of ​​oceans more than 200 years ago and is known as the Wuzhu Ocean. With the alluvial rivers, a large amount of sediment is deposited, and sandbanks are gradually formed. According to the book "Agricultural Records of the Pearl River Delta", Wanqingsha Chengsha was in the Qing Dynasty during the Qianlong and Jiaqing years, and in the 18th year of Qing Daoguang (1838), Dongguan Minglun Hall was encircled here, causing Wanqing Shaliang, Wanqingsha Town. And got its name. The term “沧海桑田” aptly summarizes the history of landform changes in Wanqingsha Town. The history of planting lotus roots in the Wanqingsha area is about two hundred years. Because of the low land yield in the area, the water is held all year round. Most of the farmland is a typical “wetland” landform. The alluvial silt is deep, the soil is fertile, and it is rich in organic matter. The content is particularly rich, coupled with a warm and humid climate, the quality of the growing lotus root is different. The lotus roots harvested in summer are crisp and white, sweet and fragrant; the lotus root starch harvested in autumn and winter is rich in content, the cooked food is loose and delicious, the musk is rich, and the astringency is pure. Through artificial and natural long-term selection, lotus root varieties suitable for the local unique ecological environment have gradually formed. Before the liberation, the lotus root cultivation was concentrated in the north of the 13th rush. After the land was built around the sea, the south tidal flat was painted year by year, and the lotus pond was followed by the south. In the 1960s and 1970s, between the 13th and the 20th, it was located in the south of Wanqingsha, and the original Xinyi Town area adjacent to Wanqingsha Town was rich in lotus roots. The area of ​​lotus root cultivation in this area reached several thousand mu. Xinyu Town has 20% of the cultivated land area and has formed a trading market. It has become a distribution center for Wanqingsha and the original Xinyi Town Lotus. The new lotus root has gradually become famous and enjoys a good reputation in Hong Kong, Macao and Southeast Asia. At the end of the 1970s, the “Xinyan Lotus” of Wanqingsha was superior to the lotus roots in the surrounding Nanhai, Shunde and Zhongshan, with its long shelf life, high starch content and unique flavor, which stood out among the many lotus root products. Since then, "Xinyi Lotus" has been well-known. In March 2002, the original Xinyi Town was merged into Wanqingsha Town. Nowadays, Wanqingsha Town is the representative of the unique Shatian water town in Lingnan. Due to the large-scale planting of lotus roots, there is a picturesque scene of “One Sichuan banana forest green, ten miles lotus flower, thousand pond fish jumping, and thousands of miles flowing”. .

In the early 1950s and early 1960s, Nansha Transportation was mainly based on shipping. In addition to local sales, most of the lotus roots produced were shipped to Guangzhou and surrounding cities and counties for sale. At this time, the popularity of Xinlian Lotus was gradually formed. In the 1960s and 1970s, the Xinyi Lotus Market was formed in the Wanqingsha area. In 1964 and 1965, the Xinlian Lotus was well-known in the Pearl River Delta. In 1966, the local government established the “Xinyi Lotus” acquisition station to organize the acquisition.
