Pop diva Sammi Cheng (鄭秀文) usually goes to bed late at night but slept at 11pm on 8th February, after finishing her work. She found it unbelievable.

On the following day, she uploaded a video on Instagram and posted a message that she trained after waking up at 6am before applying makeup and going to work: “#work is a form of motivation for sleeping early”
