Zhaoqing - Seven Star Crags
Zhaoqing is most famous due to the natural beauty of Seven Star Crags. This city can be a mix of Guilin and Hangzhou due to its odd shaped limestone formations and serene lakes in the city. The best advantage is its closeness to Hong Kong. It can be reached by rail, bus or boat from Hong Kong.
Here's Goddess Lake, which offers tranquil beauty.

Wait til they're in the middle then make it wiggle
Zhaoqing is a great 2 day escape from Hong Kong
