It was not until the sixth year of Changqing after the Guanyuan War (A.D. 160 1) that Songping Jia Bing served as the duke, which lasted for two generations. In Kuanyong 15 (A.D. 1638), Dan Yu's letters were handed down for five generations, and in Lu Yuan 15 (A.D. 1702), Matsuhei Bingji was sealed. After that, it was handed down for seven generations until the Meiji Restoration. Yancun finally ended its mission as a mountain fortress and ushered in a peaceful era. In the past 200 years, the city owners of all dynasties have built and expanded Yancun Town to varying degrees, including Benwan and Erzhi Bay. Curved wheels are set in many places outside the pill, and stone barriers are built on the cliff side. After planning, barriers were set up at important dangerous places, and the gates were constantly renovated and thickened. Therefore, until now, most of the Yancun site has been well preserved. The only regret is that Tianshou Pavilion no longer exists. You can see Yu Yue from a distance along the ruins of Yancun Town near Muzengshan Road. Shimomura-machi is bounded by Iwamura Kawamura, with Wu Jia residence in the north and shops and farms in the south. The remnants of that year and the scratches on the ground can vaguely see the prosperity of the past. The financial resources of the Francisco mainly depend on Kimura and Tosa who run the printing and dyeing industry. As an ancient building protected by the state, the structure of the printing and dyeing factory was well preserved, and some shopping malls were opened nearby for the convenience of tourists. In addition, Iwamura City is also famous for Japanese wine brewing with brands such as "Nvzhu" and "Fantasy City". Finally, I have to mention that Misako Watanabe, the mayor of Yancun, is also a woman. Maybe after a few hundred years, Yanji will be reincarnated and continue her dream of being a "hostess".
