Historical Records of Nanguangji Street

According to historical records, Chengtianmen Street at that time had a fishing ditch on both sides, covered with green slates, and locust trees planted on both sides of the road, which was also called Huai Street at that time. There are two sentences in Han Yu's "Two Poems of Early Spring by Zhang Eighteen Members of the Ministry of Water": "The sky is raining and crisp, and the grass is far and near. The most important benefit is the spring of the year, which is better than the willow. " The "Tianjie" in the poem is Chengtianmen Street, which is why Chengtianmen Street is called Tianjie. After this poem became popular, it became a trend for Chang 'an people to enjoy grass color in Chengtianmen Street in early spring.
