Juedai Shuangjiao () is a Taiwanese television series adapted from Gu Long's novel of the same title. The series was first aired on TTV in Taiwan in 1977.
The series was a major production by TTV because it involved most of the artistes in TTV at the time. Hsia Ling-ling was initially selected by Gu Long for the role of Tie Xinlan, but she ended up portraying Xiaoyuer instead. Gu Long praised Hsia's performance as "a classic of the classics". Su Ying and Murong Jiu, originally two different characters in the novel, were combined into a single role (portrayed by He Szu-min) in the series.
News of Gu Long having an affair with Chao Tzu-ching surfaced when the series was being aired in 1977. Chao was heavily criticised in the media for being a "third party" as Gu Long was already married. Gu Long had previously requested the screenwriters to give Chao a bigger role on screen. After the scandal was exposed, Chao was fired from the project and replaced by Chu Hui-chen. The screenwriters also changed the script to make Chao's character, Tie Pinggu, become disfigured.
