Because Major General Xiang Dong temporarily wanted to block the green news, almost no one knew that the smog in Beijing had already been dealt with. They always believed that such days would eventually pass!
Until people started taking air samples in the capital, wanting to know if the air had really changed!
The professors and experts, upon seeing the air test data from the capital, couldn't help but rub their eyes, feeling disbelief and shock. Because the data showed that the toxic gas content in the smog had surprisingly dropped to an unknown low level, while the negative oxygen ions in the air were incredibly high!
How is this possible?
