Yancheng belongs to Jiangsu Province and borders the Yellow Sea in the east. The whole city is flat, with canals and rich products. It is called "Land of Fish and Rice". Due to the vast coastal beaches, a large number of red-crowned cranes and elk thrive here, and Yancheng is also known as the "Oriental Wetland Capital, Crane and Deer World". During the War of Resistance against Japanese Aggression period, the headquarters of the New Fourth Army was rebuilt in Taishan Temple in Yancheng due to the Southern Anhui Incident, and it is now one of the "patriotic education bases". Because Yancheng has beautiful natural scenery and red history, many film and television dramas also come here to shoot.

Shanghai Farm in Dafeng District, Yancheng once filmed the 74-year edition of Crossing the River.

I remember a scene in which a female guerrilla captain flew into a boat with a pole. This scene was originally filmed in a reed swamp on the outskirts of Shanghai, but when reviewing the film, Jiang Qing suggested that the reed swamp was not beautiful enough and had to be filmed again.

Most of the film's creators are from Shanghai, and some of them are familiar with the Shanghai farm, saying that the reeds there are lush and can certainly meet the requirements of the head. In this way, the crew pulled to the beach outside Dafeng Salt Field and spent several weeks remaking the scene.

Shanghai Farm was approved by Chen Yi, the first mayor of Shanghai after liberation, with the number 1950. It was once the main reform and education place for criminals in Shanghai, and was once listed as a large-scale reform-through-labour unit in China by the Ministry of Public Security. Now it belongs to Shanghai Guangming Food (Group) Co., Ltd., which is the largest agricultural production base outside Shanghai and an important production base of rice bags, vegetable baskets and meat plates in Shanghai.
