Wong along with a few like-minded students founded Student Politicism on May. 26, 2020 [1], just days after the Chinese Government announced the National Security Law. The group name in Chinese means "venerate studying to enlighten mind; defend citizens to ponder politics.” As the NSL silences the city’s civic society, Student Politicism became one of the few remaining local pro-democracy organizations that continued to run street booths. She and other members were repeatedly arrested on suspicion of illegal assembly or sedition, and were warned of possibly breaching the NSL by the police. [2]

On Sept. 21, 2021, Wong reportedly turned herself to the police to be arrested after three other core members were arrested under the National Security Law the day before. The police alleged them to have incited hatred against Hong Kong's government by urging people not to use the LeaveHomeSafe Covid tracking app and calling to prepare for another "revolution" through martial arts training. Four were taken to court later, charged for inciting subversion, and all denied bail.

On Oct. 23, 2022, Wong was sentenced Sentenced for three years at vocational development training center.
