One possible version:
Recently Heng Shui has often seen the heavy smog weather, which has done great harm to our daily life. Due to the heavy smog many traffic accidents happened, and some people got injured and some even lost their lives. Besides, more and more people who are suffering symptoms related to smog have to go to see the doctor.
Now that we have realized the great harm caused by the smog, we should take measures to reduce the smog. It is vital to make it by educating people especially factory owners to raise their awareness of protecting the environment. People should go to work by bus or by bike if possible instead of driving and plant more trees to absorb and clean the polluted air. Only in this way can we save ourselves from the smog.
I sincerely hope all the citizens in Heng Shui can work together to do something to save the air we breathe every day
