The State Post Bureau lately introduced two Y8-F100 planes and one Y8-F400 for three new post-airlines including Shenyang-Shanghai-Shenyang, Shenzhen-Shanghai-Shenzhen, and Xi'an-Shanghai-Xi'an. By far, an eight-airline post-aviation net, centering on Shanghai, has been formed to cover 26 provinces, autonomous regions and municipalities.
Liu Liqing, postmaster general of the bureau, pointed out that the three new planes will provide all-round effective support to post-aviation's speed upgrade on July 1.
The three planes were developed and manufactured by the China Aviation Industry Corporation.
