Is Leng Oh (or Dragon Lake) in Chaozhou?

Based on the information I know, truly, there is an old village called Longhu Village (Dragon Lake Village) in Longhu Town, Chao'an District, Chaozhou city. But I am not sure whether the one I know is your parents' home town or not.

As I know, the public buses are not very frequent, so if you plan to go, it is suggested to hire a local car to take you to reach directly.

Thank you, Judy. In fact I went there as a child way back in 1948 and returned to Singapore in 1950. I thought of paying a visit. I remember it was more of a town with a wall and an arch gateway at its entrance. It had a main street running through with buildings on both sides. My home was located right inside an alley which was accessible through the entrance of one building.
