[3] She is also known for having been disappeared in August 2019, to publicly resurface only 14 months later at a press conference in Hong Kong, where she shared her ordeal of being held on the Chinese mainland.

[5] After she returned to Hong Kong, she volunteered with World Vision International in Shaanxi in 2004, and bought a flat in Shenzhen two years later, hoping to live there permanently.

[9] After the outbreak of protests against the Hong Kong extradition bill, Wong gained attention for attending demonstrations waving her British flag.

"[11] On 2 October 2020, Wong announced that she had returned to Hong Kong following criminal proceedings in the mainland and that she was being treated at the Tuen Mun Hospital after a scuffle with security officers.

[12] Wong also stated that she had been detained in Futian for "picking quarrels and provoking trouble" and that she was later transferred to a prison in Shenzhen before being sent to Shaanxi.

[12] In an interview with CNN in November 2020, Wong urged young Hong Kongers to leave and start a life elsewhere, while saying that it is too late for an "old woman" like her to do the same.

In late November 2020, she was nominated for the Nobel Peace Prize by the UK's All-Party Parliamentary Group on Hong Kong after her arrest.

[19] In June 2023, Wong and various other pro-democracy activists were arrested including Chan Po-ying, Mak Yin-ting, and Leo Tang.

All of the people arrested were leaders in various pro-democracy movements including the Hong Kong Journalists Association, Confederation of Trade Unions, and League of Social Democrats.

On the evening of 4 June 2024, the 35th anniversary of the Tiananmen Square protests, a woman was apprehended by police for chanting slogans suspected to be "seditious" under the National Security Ordinance.
