HONG KONG -- In the bustling city of Hong Kong, 57-year-old Leung Chi-sum has found his calling in a spirited way -- running with the Chinese national flag.

As he dashes along the city's coastline, the five-star red flag billows behind him, catching the warm autumn breeze and perfectly synchronizing with the rhythm of his heart beneath his bright red shirt.

Over the past four years, Leung has accumulated an impressive total of 1,012 kilometers, which is not merely a physical feat but a heartfelt tribute to his love for the country.

"One should be low-key in life, but high-key when it comes to loving one's country," he said.

Leung's journey began on China's National Day in 2020 during a particularly challenging period for the city. With a small group of friends, he set out to run about 10 kilometers in celebration of the country's birthday while uplifting the spirits of Hong Kong residents.

Inspired by his mainland friends, Leung decided to carry a small hand-held national flag during this run. As they waved the flag along the way, the cheers from the crowd invigorated them, making every step feel lighter.
