In November 2020, Quat said that a face mask manufacturer was challenging the
Hong Kong national security law by producing yellow-coloured masks. In December 2020, Quat asked the government to consider a "lockdown order" for foreign domestic helpers on their day off, claiming that social distancing violations were "getting out of control" by them. In response, the Secretary for Labour and Welfare,
Law Chi-kwong, dismissed Quat's idea and said that her suggestion would be inappropriate and discriminatory. In January 2021, the Hong Kong judiciary dismissed Quat's idea, in which she suggested that a council should be used to determine criminal sentencing due to a perceived lack of consistency in penalties. The judiciary responded that current appeals and reviews were effective. In February 2021, Quat said that
BBC produced "fake news" that discredited mainland China's government, and that BBC deserved to have their programming dropped by RTHK. Later, Quat said that RTHK had issues and was "left unsupervised" under its former Director of Broadcasting, Leung Ka-wing. In contrast, the RTHK's Programme Staff Union stated that they had serious doubts about the new director, Patrick Li, and that the government had made moves to strip editorial independence from RTHK. In April 2021, Quat stated that the COVID-19 situation in India was out of control, and that flights from there to Hong Kong should be restricted, despite a mandatory 21-day hotel quarantine for inbound passengers. In December 2021, it was reported that Quat was eligible to vote four times in the
2021 Hong Kong legislative election, yielding 0.0475578% of the total voting value (elected seats), which is 9569 times more than the value of an average voter's total voting value. On 5 January 2022,
Carrie Lam announced new warnings and restrictions against social gathering due to potential
COVID-19 outbreaks. One day later, it was discovered that Quat attended a birthday party hosted by Witman Hung Wai-man, with 222 guests. At least one guest tested positive with COVID-19, causing all guests to be quarantined. In February 2023, when talking about
foreign domestic helpers, Quat said she heard complaints and that "If it's not about job-hopping, it's that they don’t match their product descriptions. Let’s not say 'product,' but they come to Hong Kong and they don't know how to do any of the things they said they could do. Domestic workers' contracts, and domestic worker policies, only help the domestic worker. They don’t help the employers." In July 2023, after the government lost at an attempt to ban the song
Glory to Hong Kong, Quat said that the government should keep trying to ban the song. ==Honours==
