Haha yeah on Lantau island, just to the west of HK island.
I went there for a school trip once when I was really young. But it doesn't really come close to the scale of the Spring Temple Buddha in Henan.
Ive visited the Tian Tan Buddha many years back, as a cultural experience. Seems that there's a lot of Hong Kongers who are Buddhist , Taoist ?
I've always wanted to visit the Spring Temple Buddha in China, someday !
