Beijing had changed a lot in the past two to three years.
First of all, the roadside greenery had basically been replaced with purifying grass. This also made the air in Beijing very good. There was almost no smog most of the time.
This also made the people in Beijing very grateful to Academician Qin.
Therefore, on the streets of Beijing, some places where purification grass was planted would put up a sign to introduce the purification grass. At the same time, as a purification grass researcher, Academician Qin's photo would also be printed on the sign.
Other than the purification grass, some places, such as parks, bus stops, waiting areas ... In places like this, there would also be a lot of warm-keeping grass planted.
These thermostats grass could make the surrounding temperature very suitable. It provided convenience and help to many people in winter and summer, which was also appreciated by many people.
