A two-day promotional activity for new energy vehicles and "green travel" was held at the Qingdao Software Park in Shinan district, East China's Shandong province, from July 27 to July 28.

Officials from Shinan were able to try out the new energy vehicles and talk with the 18 exhibitors.

Shinan has encouraged domestic companies to use new energy vehicles in government offices, scientific and technological enterprises, and industrial parks so as to promote green travel in these places.

The Qingdao Software Park covers an area of 10 hectares, with nearly 200 enterprises operating there and nearly 6,000 people working at science and technology enterprises.
