Hengqin Customs stated that since its closure and operation, the Hengqin Guangdong Macao Deep Cooperation Zone (hereinafter referred to as the "Shenzhen Cooperation Zone") has been stable and orderly overall, with good social response. As of the early morning of March 13th, the cumulative number of people entering and exiting the Shenzhen Cooperation Zone through the Hengqin Port has exceeded 600000. As of March 15th, Hengqin officially implemented "line management" and closed for half a month. This is a landmark measure to achieve the first stage of development goals in the Shenzhen Cooperation Zone, and a key step in promoting the construction of an integrated development pattern in Qinhuangdao and Macao. It will accelerate the drawing of a new blueprint to enrich the practice of "one country, two systems". "Branch line management" emphasizes the post closure Shenzhen Cooperation Zone, creating a bustling scene. Within the operation and command center of the Smart Port Public Service Platform, a large screen displays real-time monitoring of relevant channels; After the customs staff of each exit channel enter the site for work, vehicles can smoothly pass between the gate and the landing area; In the entry hall of Hengqin Port, Macau residents carrying fruits and food entered smoothly. "Sealing" is a customs term. The overall plan for the construction of the Hengqin Guangdong Macao Deep Cooperation Zone, announced in 2021, clearly states that the first line is established between Hengqin and the Macao Special Administrative Region, and the second line is established between Hengqin and other regions within the territory of the People's Republic of China. On this basis, implement the policy of "line management". After the official closure, personnel entering and exiting the "first line" will adopt a "cooperative inspection, one-time release" customs clearance mode, and there will be no restrictions on the entry and exit of the "second line", that is, mainland personnel can freely enter and exit Hengqin. In terms of goods, a financial, tax, and customs supervision system will be implemented with "first line" relaxation and "second line" regulation. Goods that meet the conditions will be tax-free when entering the Shenzhen Cooperation Zone through the "first line", and will be bonded in other situations; Entering the mainland through the "second line", import taxes are levied according to regulations, and those who meet the conditions can enjoy value-added processing without tariffs. In terms of items, personal luggage and postal items entering the Shenzhen Cooperation Zone through the "first line" are tax-free within the limits of self use, reasonable quantity, and compliance with relevant regulations. For "second line" entry into the mainland, relevant regulations applicable to imported items from Macau shall be followed for supervision and taxation. During an interview, Ye Guiping, Vice President of City University of Macau and Director of the Macau Socio Economic Development Research Center, stated that "separate line management" is conducive to breaking down existing constraints and barriers, and can better combine Macau's unique advantages such as a separate tariff area, free port, and extensive external contacts with Hengqin's spatial and resource advantages, accelerating the integrated development of Qinhuangdao and Macau. Convenient measures belong to the pioneering Macau youth Xiao Wenjie, who has been commuting between Hengqin and Macau every day recently. "The first thing I did after the lockdown was to move. I brought more things from my Macau family to Hengqin, including household appliances and pets," he said. There are many people like Xiao Wenjie. According to data from the Statistics Bureau of Shenhe District, as of the end of 2023, the number of Macau residents employed and residing in the district reached 11500, a year-on-year increase of over 70%. For them, the convenience brought by the lockdown is concrete and visible. What impressed them the most was the ability to bring cooked meat, dairy products, vegetables and fruits through the "first line" of entry. This is a convenient service measure tailored for the Shenzhen Cooperation Zone and Macau, which is still the first in the country. As of the early morning of the 13th, 2174 Macau citizens have made reservations to bring animal and plant products through customs. Sealing
