Taiyuan has concentrated on improving its local environment for residents in recent years.
The Jiancaoping district, where many industrial polluters are based, has invested more than 23 million yuan ($3.4 million) on improving poor infrastructure, cleaning the air and replanting trees since March 2016.
During the first phase of the project, dilapidated buildings in an area measuring 15,000 square meters have been demolished. The local authority also renovated damaged roads as well as adding pedestrian crossings and new walkways. The land for newly-planted trees covers some 28,000 square meters with more than 1,000 trees of various kinds planted.
"We now use trains to transport coal and arrange sprinkling trucks to water the roads regularly, which reduces the coal dust in the air," said Du Haisheng, director of Jiancaoping environmental protection bureau.
Besides, Taiyuan has established and reconstructed 24 local parks, such as Yingze Park and Taiyuan Botanical Garden. The parks not only add greenery to the city, but provide comfortable public areas for locals to exercise and relax.
