Dec. 13, 2016 -- In recent years, Lhasa City has been positively promoting the construction of ecological environment in a full way. For example, "yellow label cars", namely those heavy-polluting vehicles, as well as aging automobiles and coal-fired boilers are eliminated. At the same time, green projects for mountains, rivers and landscapes are carried out, too. Thanks to the above measures, Lhasa's air and environment quality is improved obviously.
