Dear Peter，
    I'm glad what you are caring about the development of my hometown．Great changes have been taken place since the 19th National Congress of Communist Party of China．The targeted poverty reduction has reached it's ideal aims．Many poor family have got effective help from the local government and have improved their life greatly．Old houses are replaced by new tall buildings which are surrounding with green trees and colourful flowers．The rivers once heavy polluted are getting clearer and clearer．Much to our delighted，lots of fishes return to the rivers．The blue sky paints itself with colors and the birds joyfully dances with the music of gentle winds．
    Please come to visiting my hometown in the near future．
Yours，
Li Hua
