I'm just back from beach combing in my favorite beach on an island called Cheung Chau, The name translates as 'long island', but is actually dumbell shaped with a narrow sandy bar joining two islands.
I have spent many afternoons here, at high tide and low tide, sunny or rainy days. Today, I've found rare turquoise, lavender and yellow pieces, a white piece shaped like a boomerang, amongst many other perfectly frosted colorful pieces. The variety of colors and shaped never ceased to amaze and surprise me!
Do stop by this wonderful island when you visit Hong Kong!
