Shih Szu (Chinese: 施思; pinyin: Shī Sī; born October 24, 1953) is an actress from Taoyuan, Taiwan.
However, the film that would rocket her to stardom would be her appearance opposite the famous Cheng Pei-pei in 1971's The Lady Hermit.
She then would go on to appear in numerous wuxia and kung fu films such as The Thunderbolt Fist, Heroes of Sung, The Shadow Boxer, The Lady of the Law.
By the mid to late '70s, she was mostly relegated to supporting roles in films for such directors as Chang Cheh (Marco Polo, The Naval Commandos), Chor Yuen (Jade Tiger, Clan of Amazons) and Sun Chung (Avenging Eagle, The Deadly Breaking Sword).
She also began to appear in films in Hong Kong and Taiwan outside of Shaw Brothers such as The Revenger and The Heroes.
