Painted Grass by LEEYU

In one part of China,Chengdu,the workers were found dyeing those withering and yellow grasses green.They wanted to let people who passed by have the thought that the grasses were very healthy.The green dye is not toxic but is a strong dye as when it rained,the green dye would not be washed off.It could last for 10 to 14 weeks.Some residents found out that after stepping onto the grass,their shoes also turned green.Some said that this method is polluting the environment.Some even suggest to use those money to build schools instead of buying those dyes.
I think that they should not dye the grasses as they polluting the environment.They should water the plants and let it have a healthier growth.They should have spent this amount of money on other more important uses.
