How many years have there been Sophora japonica in Hongdong, Shanxi?

The locust tree in Hongdong grows in Guangjiduo, which is said to have been planted in the Han Dynasty.

During the reign of Hongwu Yongle in the Ming Dynasty, Shanxi people moved to Hebei, Shandong, Henan, Jiangsu, Anhui and other places many times. Guangji Temple set up a bureau to send personnel, and the big locust tree tied a knot to take care of the capital of Sichuan. Hongdong immigrants left their hometown step by step from this big tree and regarded the big locust tree as their hometown forever. Unfortunately, in the Ming Dynasty, the Sophora japonica was destroyed by water diversion with the temple, and the second generation of Sophora japonica withered. Fortunately, the third generation of locust trees are flourishing now. In the second year of the Republic of China, people from Jing Daqi, Liu Zilin and other counties raised funds to build a monument, which was five feet long and two feet four inches wide. The crown of the tablet is engraved with the word "memorial", the body of the tablet is engraved with five official characters, and the tablet is engraved with an inscription, briefly describing the immigration situation. There are also pavilions and tea kiosks, which are "famous slender trees" and engraved with a poem: "Woody water sources flow long. Yiyi Liu Yang recognized the village and the pedestrians returned to the front. Love and affection are better than calling Tang. " Nowadays, the annual search for the roots of Tomb-Sweeping Day has attracted a large number of descendants of immigrants to recognize their ancestors.
