BEIJING, May 6 -- China's postal and express delivery sector handled more than 4.8 billion parcels during the just-concluded May Day holiday period, marking year-on-year growth of over 20 percent, according to data released by the State Post Bureau on Tuesday.

During the holiday, the sector deepened integration with cultural and tourism sectors by innovating service modes. Multiple regions introduced a series of convenient express delivery services, including airport-based one-stop "shopping and delivery" services to improve convenience for tourists.

This sector also showcased progress in green transformation during the holiday period. In Hainan Province in south China, fully biodegradable packaging bags were widely used, while in Hangzhou, east China's Zhejiang Province, reusable boxes were piloted in commercial, governmental and other usage scenarios, which helped reduce resource consumption.

The bureau said that during the holiday, the sector enhanced its service capabilities and promoted collaborative innovation across multiple sectors under a national effort to boost consumption, connecting high-quality logistics services with new consumption scenarios -- facilitating positive interaction between improved supply quality and effective demand expansion.
