Dear David:

How time flies. How are you? I’m appreciated your great interest in the use of environment-friendly shopping bags encouraged by Chinese government.

Recently, as too much use of plastic bags has caused serious white pollution, our government encourages us to use environment-friendly shopping bags. Plastic bags are not free any more when we are going shopping in the supermarket, which exerts great effect on reducing the use of plastic bags.  Most of shopping centers are offering customers environmental protection shopping bags.

As far as I’m concerned, though it is just a small action, in the long term, it’s a very effective way to realize our dream of establishing a pleasant working and living environment.

Yours,

Li Hua
