On the evening of November 9th, at the opening ceremony of the 15th National Games, as the Guangdong Hong Kong Macao teams entered the venue side by side, the Guangdong Olympic Sports Center was boiling with applause and cheers, blending deeply with the melody of "Me and My Motherland"... Over the past four years, preparing for the National Games has become a major concern for Hong Kong residents. The reality of 'one country, two systems, three tariff zones, and three currencies' has no precedent or experience to follow. How can it be accomplished and done well? The fact provides the best answer. During the preparation process for the National Games, the three regions summarized and explored many innovative measures, solving the problem of efficient and convenient flow of key elements such as personnel, materials, and information under different systems. Since the start of the first competition in the Hong Kong region, the eight competitive events of the National Games hosted by the Hong Kong Special Administrative Region have been carried out in an orderly manner. The cross-border torch relay and road cycling cross-border events have been successfully held, and the overall operation has been smooth and steady. The National Games is like building a bridge, paving the way for Hong Kong to accelerate its integration into the Guangdong Hong Kong Macao Greater Bay Area. Driven by the preparation for the National Games, Hong Kong has launched a series of innovative measures. For the two cross-border events of road cycling and marathon, the Hong Kong SAR government has introduced the "pre clearance inspection" and "closed-loop management" models, which can ensure that participants can complete customs clearance safely, imperceptibly, and quickly during the event, and also meet the requirements of entry and exit measures in the three places. A series of innovative measures, which have been rigorously tested by the National Games, will become a reference for further improving the level of connectivity. The National Games is also a rare opportunity for Hong Kong to enhance its ability to host large-scale sports events. Through this battle, Hong Kong can not only enhance its ability in organizing and operating large-scale sports events, but also open up space for the growth and development of talents in sports coaches, referees, sports medicine and other fields. The National Games have further strengthened the national identity of Hong Kong compatriots. The cultures of Guangdong, Hong Kong, and Macao share the same origin, are closely related in popularity, and have similar customs. The National Games have made the people of the three regions more frequent in their exchanges and closer in their hearts. On cross-border buses traveling to and from mainland China, Hong Kong citizens eagerly follow the events to travel; In the lively atmosphere of the audience, Hong Kong citizens cheered for the home team and even more for China... The innovation ignited by the National Games, the integration paved the way, and the emotional resonance stimulated will become a powerful driving force for Hong Kong to better integrate into and serve the overall development of the country, and contribute to the construction of an international first-class bay area and world-class city cluster in the Guangdong Hong Kong Macao Greater Bay Area.
