Zhongshan's South District hosted a groundbreaking ceremony for 12 key construction projects on February 25, with a total investment of 640 million yuan.

Drawing significant public interest, the Caobian Secret Realm project will transform the waters near the Caobian Village mines into a diving base.

It features an underwater art gallery and deep-experience products such as paddleboard yoga, themed dives and floating cinemas, with complementary offerings including floating cafes and aesthetics workshops.

Trial operations are expected to begin around this year's May Day holiday, initially catering to group and private clientele before opening to the general public.
