It has been thirty years since China started reform and began a policy of opening up China to the outside world.This has resulted in great changes taking place in various fields.With the nine-year compulsory education(九年制义务教育) programall children have the chance to be educated.In the past 30 yearsChina has made great progress in science and technology.In 2003China launched its first manned spaceship and fulfilled its first space walk in 2008.As economy is developing fastpeople's living conditions have greatly improved.In additionthere have also been great changes in sports.The 29th Olympics were successfully hosted in Beijing and Chinese athletes won the most gold medals.I'm really proud of the great achievements in the past 30 years.It is the leadership of the Communist Party and the great efforts of us Chinese people that made all these possible.Nowadayspeople are working hard towards a more advanced and harmonious society.I'm sure China will have a brighter future and Chinese people will live a happier life.
