1. Yingcheng Fort: Yingcheng Fort was built during the Second Opium War. It is located near today's Bayi Salt Field and was demolished during the Cultural Revolution. 1956, the coastal defense artillery stationed in Hangu built a mound gun shed with a length of1000m and a height of 8m here for training, and built several hidden howitzers in Fiona Fang. 1958, the volunteers who returned home in triumph were stationed in this barren, barbaric and overgrown saline-alkali land. The blue sky was used as a bed, the wind combed my hair, and the rain and snow washed my face. I struggled hard in the summer cold, accompanied by shovels and baskets. I took off bricks to build houses, reclaimed wasteland, padded low-lying areas and repaired salt flats. I worked hard to build a salt field covering an area of 10 square mile, and named it "Bayi Salt Field".
2. Hangu Salt Industry Customs Zone: A salt industry customs tourist zone located in Hangu Yantian, which is famous at home and abroad for its 1000-year-old salt-making history, the highest modern salt-making level and the best salt quality, with a total area of 139 square kilometers, accounting for 32.5% of the total area under its jurisdiction. Visitors can enjoy the magnificence of vast reservoirs, towering salt collection hills, salt mountain and brine sea, as well as modern technological processes such as mechanical salt mining, salt scraping, salt transportation, salt washing and double-arm machine stacking. Modern salt-making technology has become a "popular science education base for teenagers" and is favored by primary and secondary school students.
