It’s not difficult to believe that Eric Tsang only manages to get three hours of sleep in a day, at times.

As the general manager of Hong Kong broadcasting company TVB, as well as doing his other celebrity-related jobs such as hosting, the 69-year-old has lots of things to do.

A person who got to work with Tsang recently shared on social media what she saw of his packed schedule, as reported by Singapore portal 8days.

She apparently had the chance to shoot at Tsang’s house, and was impressed with the actor's work ethic and attitude.

She was quoted: “Basically, he wakes up at 6am to play golf, goes for rehearsals at 11am, films a short video till 6pm.

"He has an hour or an hour-and-a-half to eat and do his hair and makeup, then he holds a live stream from 7.30pm till 1.30am.”

On that day, he continued his duties by attending a celebratory dinner which went on past 3am.

The next morning, Tsang was up early once again to play his usual round of golf.

Throughout the day too, she observed that Tsang “didn’t get to rest at all” and took very few toilet breaks.

What was most extraordinary to her was how Tsang remained lively throughout the day even though he must have been tired.

Hopefully Tsang can keep his energy going, what with the recent report that the broadcaster experienced a record loss of RM453mil. This resulted in a decision to cut 5% of staff and reduce production costs.

Tsang must surely have even more things on his plate right now.
