Chief Executive John Lee was in Sha Tin on Saturday to meet residents and stall owners, as part of his consultation work for the Policy Address in the middle of next month.

In a couple of hours, he went to a wet market, a day-care rehab centre and two public housing estates, Wo Che and Sha Kok, meeting a family.

Lee said he wanted to learn of people's needs, their everyday life and get their views and see if they have issues the government can help resolve.

In a light moment he shared with children at a park, Lee told them not to spend too much time playing video games.

"Work hard on your studies, alright? Be good to your parents. But other than video games, do more exercise. Nowadays, our athletes get very good results. So you can also exercise to keep fit," he told the children.

Flanked by three ministers who went to Sha Tin with him, the CE also told reporters that another family he met got a public flat because of government efforts in tackling tenancy abuse.

He said such efforts in the past two years had helped recover around 5,000 public flats, and officials will continue to tackle the problem.

"Five thousand units is like a mid-sized housing estate... In recovering these flats, we helped 5,000 households," Lee told reporters.

"If two or three people live in each of them, that means we helped up to 15,000 residents. We'll keep working on this."

Lee added that government officials are in discussion with New World Development about its application to transfer the group's entire stake in the Kai Tak Sports Park to its main shareholder Chow Tai Fook Enterprises.

He said he hopes the developer can convince the authorities that the transfer won't affect the park's opening and its operations.
