China continued their dominance of the diving events at the World Aquatics Championships in Gwangju by adding two more gold medals on day four.
The sport's undisputed powerhouse nation has now won all seven events contested so far at the South Korean city's Nambu University Municipal Aquatics Center.
Wang Han and Shi Tingmao won the women's three metres synchronised springboard competition after a flawless performance saw them end on 342.00 points.
Shi, a double Olympic gold medallist from Rio 2016, has now won seven world titles while Wang has claimed three.
After the event the winning duo claimed they had prevailed despite struggling with injury.
"We not only had injuries but also fatigue and stress," Wang said to Xinhua.
"We had to use our own time to recover.
"Every day, we trained very late.
"And then we went to the medical centre.
"A lot of time was taken away.
"I had to sleep as much as possible to cure my injury."
Shi added: "It was important for me to get a gold medal.
"But what's more important is to pass the spirit of the Chinese diving team down to the next generation.
"You cannot restrict yourselves to just winning gold medals.
"You should see more than this.
"Enjoy the diving and the Games."
Shi has now won the event for the last four editions of the World Championships, with Chang Yani in 2017 and Wu Minxia in 2015 and 2013.
Canada's Jennifer Abel and Mélissa Citrini-Beaulieu won silver on 311.10 as Mexico's Paola Espinosa and Melany Hernández took bronze on 294.90.

In the men's synchronised 10m platform China's Cao Yuan and Chen Aisen claimed a huge victory over the rest of the field.
Both men boast two Olympic gold medals each and now five world titles between them after their tally of 486.93.
