Silang tanmu

Silang tanmu is a Peking opera play inspired by The Generals of the Yang Family. It has been repeatedly banned in China.

Plot
Inspired by episodes from the Ming dynasty historical novel The Generals of the Yang Family, the play is set in the Song dynasty under the rule of Emperor Taizong and contains thirteen distinct scenes.

The titular protagonist of the play, Yang Yanhui, also known as Yang Silang (杨四郎), is a Song Chinese general who is captured by Liao troops. He keeps his true identity a secret and marries the daughter of the Liao empress, Princess Iron Mask (铁镜公主, a dan role). The two dynasties come into conflict again fifteen years later; Yang briefly visits his family with his wife's help but eventually returns to enemy territory. He is initially condemned to death by his mother-in-law but is let off with a warning after the princess intercedes on his behalf.

Performance history
Silang tanmu was first staged in the mid-Qing dynasty, albeit in a "provincial" form of Peking opera. Due to its portrayal of a general surrendering to the enemy, the play has been repeatedly banned in China; the Republic of China governmental department in charge of cultural policy in Tianjin, for instance, banned the play in 1945 because it "distorted the normal ethics and morality". It was banned yet again following the Chinese Communist Revolution and the establishment of the People's Republic of China.

The ban was briefly relaxed in 1956, as part of the Hundred Flowers Campaign, although playwrights were nonetheless obliged to amend some of the dialogue. The first post-ban staging of Silang tanmu in May of the same year was watched by approximately two thousand people. The play continued to be performed until 1960, following which it apparently "incurred official disapproval once more".

Adaptations
The play has been performed in various other forms of Chinese opera, including Hebei opera, Shanxi opera, Shaanxi opera, Min opera, and Sichuan opera.

A Cantonese film adaptation of the play, was released in 1959. It was directed by Wong Hok-sing and stars Ma Sze-tsang, Yu Lai-jan, Lam Ka-sing, Fung Wong-nui, and Poon Yat On. In the film, Yang is coerced into marrying the Liao princess. She is subsequently visited by one of Yang's sisters-in-law, who persuades her to allow Yang to return to his home to visit his ailing mother. A sequel was released in the same year.
