On July 3, China Post launched "Wushan-Nanjing" charter flight route for crisp plums produced in Wushan, Chongqing. This is the first all-cargo air route that China Post has launched for Chongqing Municipality to sell its high-quality farm produces of origin to other parts of China, and the fifth charter flight route for summer EMS fresh delivery this year, after the ones for lychees from Hainan, cherries from Yantai, lychees from Guangxi and cherries from Dalian. This route radiates out to North China, East China and South China. Therefore, the fresh plums can take night flights and reach more first- and second-tier cities next morning. Moreover, the carrying capacity has doubled.

The crisp plums of Wushan county used to be shipped by the local postal enterprise to Chongqing Jiangbei International Airport, and then transported to other areas of the country via flights of China Postal Airlines on "Chongqing-Nanjing" route. The transporting volume has been increasing since 2018. This year, the county government of Wushan joins hands with the postal enterprise to boost rural revitalization. Taking advantage of the origin of the fruit and the local airport, they manage to have the crisp plums take the cargo flights of China Postal Airlines directly from Chongqing Wushan Airport, to further accelerate the distribution of the fruit.

The "Wushan-Nanjing" charter flight route for crisp plums of Wushan is operated by Boeing 737-800 aircraft. A total of 15 flights have been arranged for the season when the plums become ripe. In addition, Chongqing Postal Branch has opened three direct cold chain land routes from Wushan county to Chongqing, Chengdu and Wuhan, further extending to Central China and Sichuan-Chongqing region, with an average daily transport capacity of over 40 tons. In the plum growing area, the postal enterprise in Wushan has expanded its collection service by adding 50 new collection points to the existing postal outlets. The postal enterprise has also sent special personnel and vehicle there to provide door-to-door service. From fruit harvest, selection and packing to loading and transportation, it has facilitated the "first-mile collection service" in the main production areas, thus helping cut transportation time and improve collection efficiency.
