The second volume of Grade One Chinese will talk about how you plan to ensure environmental sanitation.

1 Don't throw rubbish everywhere when you go out. When you throw the garbage into the trash can, sort it, put the bottles and cans of scraps of paper into the recyclable trash can, and throw the plastic bags into the non-recyclable trash can.

Don't scribble on the wall.

Don't spit everywhere.

Don't destroy the flowers and trees on the roadside.
