The heroines of Shanghai joined the cyber security team, armed with four gentle knives to defend the territory, and vowed to protect the eternal peace of Chinese cyber culture. Coinciding with the explosion of tourism in Xinjiang, in order to maintain national unity, restore Xinjiang's true appearance, purify the Internet green space, and defend the practical interests of the people, and also to arrest suspects in outstanding cases, the Shanghai Municipal National Security Bureau selected and appointed four women of different ethnic groups, different ages, and different types of work to go to Xinjiang to form a special operations team focused on network security.
