Since the comprehensive resumption of customs clearance on February 6, 2023, Hong Kong's exchanges and exchanges with the mainland have become increasingly close, economic and trade cooperation has become more frequent, international events are in full swing, and consumer vitality continues to be released. Hong Kong leverages its advantage as a "super contact" to write a new chapter in its integration into the overall development of the country. After a year of full resumption of customs clearance with dense fireworks and smoke, various ports were bustling with people. Hong Kong citizens heading north and mainland tourists heading south have sparked a new wave of door-to-door visits between Hong Kong and mainland China, especially with mainland cities in the Guangdong Hong Kong Macao Greater Bay Area. The trend of Hong Kong people heading north is becoming increasingly popular, shifting from leisure consumption to daily consumption, from eating, drinking, and entertainment, to reverse purchasing and seeking medical treatment. Recently, in various popular business districts in Shenzhen, Hong Kong style people carrying backpacks and sneakers can be seen everywhere, holding hand cranked drinks in one hand and seasonal internet celebrity delicacies in the other. "Taking the subway from Admiralty Station in Hong Kong takes one hour to reach Futian Port. Shenzhen Metro Line 4 goes directly to the Convention and Exhibition Center. After work, you can go to Shenzhen for a hot pot meal and return to Hong Kong that night," said Chen Yingling, a Hong Kong resident who works as a civil servant. "The rise of 'northbound' consumption, from the perspective of 'Greater Bay Area people', everyone is a family. The more you buy my things and I buy yours, the more it can promote mutual recognition and integration," said He Liangliang, a commentator on Phoenix TV. This year, the Hong Kong section of the Guangzhou Shenzhen Hong Kong high-speed railway opened three new lines, namely Guangzhou East, Chengdu East, and Zhanjiang West, adding a total of 16 stations. At present, 73 stations across the country, including mainland cities in the Greater Bay Area, can be directly reached from West Kowloon Station in Hong Kong, and the "Greater Bay Area on the rail" is developing rapidly. "Within a year of fully resuming customs clearance, the Hong Kong section of the Guangzhou Shenzhen Hong Kong high-speed railway carried over 20 million passengers, breaking the record since its opening," said Zhang Zhiqiang, the transit railway manager of Hong Kong Railway Limited. In July 2023, the policy of "Hong Kong vehicles heading north" was implemented. According to statistics from the border inspection station of the Hong Kong Zhuhai Macao Bridge, in 2023, the number of inbound and outbound passengers passing through the Zhuhai Highway Port of the Hong Kong Zhuhai Macao Bridge exceeded 16.3 million, and the number of inbound and outbound vehicles exceeded 3.26 million, which is 1.29 times and 3.8 times that of 2019, respectively. As Hong Kong residents move northward for consumption, a new normal has emerged for mainland visitors to Hong Kong. Tourists who used to concentrate on shopping in the city center of Hong Kong now flock to various areas for meals, tea, hiking, and a deep experience of local culture. "The mountains and forests in Hong Kong have been designated as 24 country parks, and the hiking trails are also unique and mostly well-equipped, attracting more and more mainland Chinese people to come and take photos," said Hong Kong Legislative Council member Yao Po liang. After the full resumption of customs clearance, many activities that had been interrupted for nearly three years have resumed, with art exhibitions, sports events, entertainment activities, and over a hundred mainland cultural and tourism promotion events held in Hong Kong. It is understood that in the first half of 2024, Hong Kong will hold over 80 large-scale events, covering culture, arts, sports, economy and finance, etc. Hong Kong's role as a "super contact person" fully leverages its advantages of being backed by the motherland and connecting with the world, further promoting exchanges and interactions between mainland China and international partners. these
