Dear Uncle,
I’m very glad to receive your email.
Great changes have already taken place since you left. Our living conditions are getting better and better.  Villagers have moved into big and comfortable houses, many into well-equipped blocks of flats.  And almost all have been equipped with telephones. They have not only bought color TV sets, but also washing machines, fridges, and etc.  Wide roads have been built to connect villages and towns . Some families have got their own tractors, trucks and even cars.  Besides, children can now enjoy very good education.
Our government cares very much about the reconstruction of our countryside.  We are speeding up the citifying of the villages.
I hope that you and aunt will come back and have a visit to the new village.
Best wishes,
Yours,
Xiao Dong
