Just moments after the pair posed for photographs, disaster struck.
Both Mr Liu Shujian, 21, and Mr Gao Yang, 20, had made their way dangerously close to the waters at Promthep Cape in Phuket, Thailand.
On Wednesday at about 5.30pm, they slipped and fell into the sea, reported news site PhuketWan.
Mr Liu survived but Mr Gao was still missing at press time. Mr Liu said he tried in vain to save his friend.
Seeing that Mr Gao could not swim, Mr Liu, who managed to grab on to some rocks, extended his hand in an attempt to haul him out of the sea.
