Chan Wing has lived in Shui Hau, just outside Mui Wo, all his life. So had his father, grandfather and great-grandfather before him. But in the past decade, 50-year-old Chan has seen the population in the village shrink from more than 500 people to about 200 - with a predictable effect on the small businesses serving the area, including his own.
Chan knew something had to be done to prevent his community from fading away.
'There are two things I know from living here so for many years: the best ways to dig up clams and the best ways to cook them,' he says.
So two years ago, he and his wife closed their tiny convenience store and started a new business renting clam-digging tools to visitors and turning their catch into tasty dishes for a small fee.
Chan dubs his operation the 'tourist welcome centre', and even watches over his customers' belongings while they're out digging for clams. 'Mr Chan has definitely helped stimulate the weekend tourist trade,' says Louise Preston, a long-time resident of south Lantau. 'I've seen as many as 100 visitors eating clams at his place on Saturday evenings.'
Major developments such as Chek Lap Kok Airport, Tung Chung new town and the Ngong Ping 360 cable car have transformed large swathes of Lantau, but to villagers such as Chan, the south of the island has been suffering from neglect.
