A Beijing, matsalar taba sigari ta kasance mai dacewa. Koyaya, alkaluman karshen shekarar 2015 sun karye.
Don kawar da wannan matsalar, an kirkiro wani aiki don ƙirƙirar hanyoyin iska, magoyan bayan titi waɗanda zasu tarwatsa hayaƙi da hayaƙin mai cutarwa daga kamfanoni. Hakanan an tsara hanyar sadarwa na mataimakan mataimaka.
Irin wannan aikin an aro shi ne daga Shanghai da Fuzhou, inda tuni magoya bayan titin ke yakar hayaki, rage saukar da zazzabi da tsabtace shi daga hayaki mai illa. Ci gaba ya riga ya fara, amma ba a sanar da ranar ƙarshe don kammala aikin ba.
