Xiagu Danxin

Xiagu Danxin (俠骨丹心), literally Chivalrous Bones and Loyal Heart, is a wuxia novel by Liang Yusheng. It was first published as a serial between 5 October 1967 and 20 June 1969 in the Hong Kong newspaper New Evening Post. It is the tenth instalment in the Tianshan series, serving as a sequel to Fenglei Zhen Jiuzhou, and followed by a tetralogy starting with Youjian Jianghu.

Set in 18th-century China, the novel follows Jin Zhuliu — the son of Jin Shiyi and Gu Zhihua, the protagonists of Yunhai Yugong Yuan — as he roams the wulin and becomes entangled in conflicts between rebel forces, the Qing government, and rival sects. The story intertwines martial-arts adventure with themes of loyalty, integrity, and resistance to tyranny, which are characteristic of Liang Yusheng's later or "mature" phase of writing.

Xiagu Danxin has been recognised by scholars and critics as one of Liang Yusheng's more cohesive ensemble narratives, exemplifying his blend of historical realism and idealised chivalric ethics. Retrospective commentaries in Hong Kong and Taiwanese cultural journals regard the work as representative of late-1960s newspaper serial fiction and a reflection of changing ideals within modern wuxia literature.
