Jing-Jin Derby, also known as the "Golden Cup" in Chinese, is one of the most prestigious horse racing events in China and has been held annually since 1975. The event takes place at the Lingling Racecourse in Beijing, which was founded by Ye Jianlian, a famous Chinese entrepreneur and businessman.

The event starts on the first Saturday in October each year with a parade to mark the start of the race week. On the day of the race, the horses are led into the paddock for their pre-race warm-up before they begin running in the main course. The race is run over a distance of about 20 miles, with the winner receiving a gold medal and a cash prize of 1 million yuan (around $16,800).

The Jing-Jin Derby is not just a race; it's a spectacle that attracts millions of spectators from all over China. The event features a wide variety of horses, including some of the most famous in the world, such as the Gold Cup-winning stallion "Caiyuan Long", who has won numerous races throughout his career.

In addition to the excitement of watching the horses run, there is also a strong sense of community among the racers and fans. The event has become a platform for promoting sportsmanship and encouraging athletes to compete at their best.

However, the event also faces criticism for its lack of transparency and fairness. There have been reports of corruption and financial fraud during previous editions of the event, leading some to question its integrity and fairness.

Despite these concerns, the Jing-Jin Derby remains a beloved event in China, with many people attending to witness the excitement of the raceweek. As the years go by, the event continues to grow in popularity and prestige, attracting top-level horses and athletes from around the world.
