For example, "Sha-Jia-Bang" was originally called "The Sparks in the Reed Marshes", which was an adoption from a play in Shanghai Opera. There were other modern plays such as "Dai-Nuo", a story of a young minority doctor, "Jian-Gan River", a story of a Beijing suburb village with a sense of class struggle, "The Sixth Gate", an account of Tianjin rail workers' struggle in the "old society", "Jie Zhen Guo", a story on Tangshan coal mine workers during the anti-japanese war, and "The white haired girl". They were also great successes but not that famous than the model plays and gave ways when the model plays were on stage. All model plays were shot in color films. There was a period in the mid-70's when one month in each summer was assigned the month of modeal play film season. The model play films were shown in cinema, closed or open field, day and night.
