In 2021, Keung declared: “I believe Hong Kong singers can definitely become Asia’s top again.” That year, their fandom became a Hong Kong cultural phenomenon.
Fans poured into shopping malls to support their events, with some making and buying advertisements to celebrate their idols' birthdays.

Talk of the group offered many Hong Kongers an escape from downbeat news about COVID-19, political challenges and social changes facing the city.

A giant video screen fell from the ceiling during a concert and struck two backup dancers, leaving one of them, Mo Li, severely injured. The band subsequently stopped their public appearances for two months. Hong Kong authorities have charged workers from the concert's principal contractor alleged to be responsible for the accident. Last month, Li's father said his son had taken his first steps with the help of an exoskeleton device.
