Teenage sensation Nguyen Thi Kim Tuyen smashed two records at the National Swimming Championships in her native HCM City on Thursday.

The 18-year-old broke her own national record by clocking a time of 28.22sec in the women's 50m butterfly event. Thirty minutes later, she set a new national record in the women's 100m freestyle event with a time of 58.44sec.

Her result helped consolidate her team's position at the top of the rankings.

Hoang Quy Phuoc, returning to Viet Nam after a training camp in China, won his second gold medal in the men's 50m butterfly event with a time of 25.66sec. He also sealed a gold medal for Da Nang by finishing first in the men's 4x400m relay. With two more golds, Da Nang comfortably retained second place in the team's competition.
