beach (especially the ones we need to take a small boat to get to in sai kung)
yum cha (their favourite is jumbo because of the boat ride)
playtown
libraries
neighbourhood playgrounds
public pools (especially the one in ma on shan... it's HUGE!)
taking public transport anywhere, especially the tram on hk island, double decker buses, or the mtr
taking the ferry to discovery bay to see their friends

walking along the waterfront in sai kung on weekends when they can see the fishermen with all of their catch
taking our dogs for a walk with their daddy
