"I may be all grown up and have my own children, but I'll always be my parents' little one. I love you, Mommy and Daddy," she wrote on her Instagram on Wednesday with 914,000 followers as she shared family photos taken in Phu Quoc.
Her family enjoyed the sunset on the beach and visited many tourist attractions in the island.
Well known for its long, sandy beaches, turquoise waters and dense forests, Phu Quoc has become a popular holiday destination for both domestic and international tourists.
Last year, a series of Asian celebrities flocked to visit the island.
Phu Quoc has been suffering a slump in visitor numbers last year as tourists voted with their feet amid soaring airfares, exorbitantly priced hotels and various scams.
However, the island has seen signs of tourism recovery during the New Year holiday.
Born in Vancouver of Canada, she is a familiar face of TVB.
In 2018, Linda Chung made headlines when she announced that she was parting ways with TVB after working with them for 13 years.
Her husband is a doctor with a wealthy background. She has three children, two girls and a boy.
