There are also the Sui and Tang Dynasties Romance Series, the Sui and Tang Dynasties Romance Sequel, Tang Dynasty Thunder and Xue Jiajiang.
The Three Heroes Fighting Sword, The Legend of Tonglin, The Legend of Iron Umbrella and The Water Margin are short in length, but I think they are relatively classic ballads.
There are also Zhang Shaozuo's "Kunlun Swordsman", "Yongzheng Swordsman Map" and Tian Lianyuan's "Shu Jian An Qiu Lu" which are also very good.
Yuan Kuocheng's Romance of the Three Kingdoms is a masterpiece of storytelling and storytelling.
Dan Tianfang's "Love in Daming"
There are Li Zicheng and Lian Liru's The Great Sui and Tang Dynasties, Liu Lanfang's Yang Jiajiang and Yue Fei's Biography. I especially recommend Tian Lianyuan's Outlaws of the Marsh, Yang Jiajiang and The Romance of Sui and Tang Dynasties, all of which are humorous.
