In the 1950s, Shanghai Science and Education Film Studio began to try underwater photography. Gaoxiang was one of the first batch of people who set foot on the South Pole. Under extremely difficult conditions, he recorded the natural landscapes as well as animals and plants in the South Pole at a close distance. Compared with the 1551 Diary of Emperor Penguin, Gao xiang's film about penguins was 20 years earlier.
