NO.227

Maybe this is an example that other people called it  "Domino Effect" or  " Butterfly Effect".(The two "effect" is I quote from another attendent)
Sometimes we only take our own benifits into consideration. Throw the rubish on the ground, spitting and other bad behavior. But we can't think oneday maybe there are some same things of similiar things happen on you or you will be affected bad result of the bad behavior. There are some old saying:What goes around comes around.  A bad beginning makes a bad ending(恶其始者必恶其终。).One good return deserves another(善有善报，恶有恶报 ). They can show tell us how to be a person.
So during our life ,we should do something good while don't neglect the details.

And last I want to way ,smoking is a bad thing.~~
