Second edition changes
This novel was first written in 1963 for South-East Asia Weekly, a joint publication of Hong Kong's Ming Newspaper and Singapore's Nanyang Business Newspaper. In 1970, Jin Yong began revising all his works, including Mnemonic of the Linked Cities.
The original title of this work was Suxin Jian, or The Pure-Heart Sword. It was later changed to Liancheng Jue (The Secret Treasure Palace and similar variations in English) during the revision process.
