In the early days of liberation, the CCP's underground workers in Taiwan, represented by martyrs such as Wu Shi, Zhu Feng, Chen Baocang, and Nie Xi, lurked and fought hard on the isolated island of Taiwan shrouded in white terror, taking risks to deliver key intelligence. In 1950, due to Cai Xiaoqian's rebellion, the organization was devastated, more than 400 people were arrested, and the blood of many patriots was shed in Racecourse Town, Taipei. They shouldered the mission of their country and country, held fast to their faith in the dark night, and forged loyalty with their lives until they died heroically. This tragic history is a monument of blood and fire in the common memory of both sides of the Taiwan Strait, and it still stirs people's hearts.
