About some poems named after cities,

Nanjing: Four hundred and eighty halls in southern dynasties, with many terraced fields and misty rain. (Du Mu)

Jinan: Lotus flowers on four sides and willow trees on three sides. One city has mountains and half a city has lakes. Taiyuan: crossing the mulberry dry water for no reason, looking at Bingzhou as my hometown. Yichun: Not far from Yichun, Jiangshan wins many lines. Chengdu

Look at the red and wet place, the flowers in Jinguancheng are heavy.
