Fengyun Leidian

Fengyun Leidian (風雲雷電), literally Wind and Cloud, Thunder and Lightning, is a wuxia novel by Liang Yusheng first published as a serial in the Hong Kong newspaper Ta Kung Pao from 9 February 1970 to 31 December 1971. Set in 13th-century China during the Song dynasty, it follows a group of martial artists who join forces to resist invasions by the Jin and Mongol empires. The novel is loosely connected to Liang Yusheng's other novels set in the Song dynasty, including Kuangxia Tianjiao Monü, Hanhai Xiongfeng, and Mingdi Fengyun Lu.

The story combines historical and martial arts elements, makes references to characters from the classical novel Water Margin, and depicts its four central heroes — nicknamed Wind, Cloud, Thunder and Lightning — as representatives of unity and patriotic resistance. Critics and scholars have described Fengyun Leidian as characteristic of the later or "mature" phase of Liang Yusheng's writing career. While praised for its ambition and historical imagination, it has also been noted for its length and diffuse narrative focus.
