Zou Xun, a resident from Mingyu Nanqiaolijing, Chongqing, received a package labeled "fast delivery of pre-sold products" on November 6. It was a mobile phone sold in advance of Double 11.

Through sorting at two places, both the efficiency and accuracy of package delivery were enhanced.

"Scores of products were released in advance this year, and they can be shipped as soon as customers pay a deposit," said the person in charge of Cainiao Network Technology Co., Ltd. Products pre-sold for Double 11 had been delivered to communities, warehouses, or other spots near consumers in advance, so they could receive their packages soon after paying the retainage.

To speed up the delivery of goods during the Double 11 shopping festival, express companies in Chongqing were equipped with intelligent devices. Through sorting at two places, both the efficiency and accuracy of package delivery were enhanced.

Packages sent to Chongqing from all over the country are first sorted at the Huixing Center of Chongqing Branch of China Post Group. At 14:00, November 9, the reporter saw packages fall into reusable environment-friendly bags labeled with different addresses through a conveyor belt after a special camera identified them.

"High-speed double-layer package sorting machines are the latest intelligent products used in the city's express industry, which realize automatic sorting," said the person in charge of the Huixing Office, "in each machine, there is a special camera that can scan the bar code of one package at a time."

A package of fresh food to be sent to No. 1, Liyuchi Village 4 fell into the bag labeled "Liyuchi" automatically, and then it was loaded onto a vehicle for delivery.

At 16:00, a total of 2,500 packages of fresh food were transported to the Liyuchi Center for secondary sorting. As they moved along the conveyor belt in an orderly fashion, the couriers standing on both sides sorted them according to their labels of addresses. Manager of the center Liao Yu told the reporter that, in this way, the packages could be sent accurately to their corresponding communities or even buildings.

After sorting, couriers will send the packages to the community lockers, postal express supermarkets, or Cainiao Post. For residents' convenience, many of the city's express service agencies have extended their business hours to 23:00.
