There is a furniture factory named GUANGZHOU HANLIN FURNITURE ENTEPIRE COMPAY LTD. The factory release the poinous gas at the time off work,usually from 6pm to late at night every day.
When I smelled the gas,I feel headache and cough,seem cathched a cold.I can not sleep at night.Our colleages had called the EPA of HUADOU and called the hotline of the mayor of GUANGZHOU many times.But it is no use.I love my county,and I believe that my life will be better,but the thing I met let me feel uncertain. How can We do about it,there are somebody can help us?
