Cheng, usually stands as a flag bearer in air force uniform, has fulfilled near 100 tasks since joining the honor guards in early 2014.

Cheng, who is about to turn 30 in December, is single and too busy to start a relationship. She hasn't taken any vacations during the past two and half years.

"My parents are a little worried, but they have always been supportive of my work," said Cheng smiling.

"The thought of leaving the honor guards has never occurred to me, and I wish every task I attend to be flawless and amazing," Cheng added.
