Jing-Jin Derby is one of the most iconic and prestigious horse racing events in China, held annually at Sha Tin Racecourse in Hong Kong. The event features the famous "Jing-Jin" colt, who has been the subject of much speculation and debate over the years due to his unpredictable behavior and lack of genetic compatibility with other horses.

The Jing-Jin Derby is not just about the race itself, but also about the tradition behind it. It dates back to the early 1960s when the first official races were held at Sha Tin Racecourse, and has since become a major event in the Chinese horse racing calendar. The event attracts thousands of spectators from all over the world and is seen as a symbol of China's rich horse racing heritage.

One of the main reasons why the Jing-Jin Derby is so popular is its high stakes and prize money. The winner of the event can earn up to RMB 2 million (US$35,000) and can even be declared the champion of the year. This makes the event one of the most lucrative races in the world.

Another reason why the Jing-Jin Derby is so beloved by fans is that it showcases some of the best horses in the country. Many of the leading jockeys and trainers have been involved in the past few decades, making the event a true showcase of talent and skill.

Despite the popularity of the Jing-Jin Derby, there have been several controversies surrounding the event. For example, there have been reports of horse doping in recent years, which has led to concerns about the fairness of the race and the integrity of the horses participating in it.

However, despite these challenges, the Jing-Jin Derby remains a beloved event for many people in China. Its reputation as a prestigious race and its close connection to China's rich horse racing history make it a source of pride for the country.
