     Do you still remember the terrible earthquake in 2008 in Sichuan, which killed at least 87,000 people and

left millions homeless? On the twelfth day after the earthquake, Premier Wen Jiabao said, "A new Wenchuan

will rise from the ruins (废墟)." Now his words have come true. Three years has passed and the worst-hit

areas in Sichuan have risen from the ruins.

     So far, 95% of the reconstruction projects (重建项目) have been completed. Nearly 3,000 schools, 1,000

hospitals and more than 5 million homes have been built. Now everyone has been provided with a home, a job

and social security (社保).

     Dong Xinjun, a villager in Qingchuan, said volunteers from Zhejiang taught him how to grow mushrooms

and now he makes about 3,000 yuan more than before every year.

     Zhu Lihu, the headmaster of a village primary school in Qingchuan, told us that teaching equipment had

been greatly improved. Now they have new classrooms, a library and a computer room with 20 computers.

     On May 8th, 2011, Premier Wen Jiabao made his 10th visit to Sichuan Province after the earthquake. He

visited a lot of middle schools and neighborhoods. At Beichuan Middle School, Premier Wen embraced a

student named Zheng Haiyang, who lost both of his legs in the earthquake. The students told Premier Wen

that their new school was very beautiful. And they would never forget that it was built with the hearts and

strength of people across the whole country.

     Premier Wen believes that the people in Wenchuan have a "strong will" and a "bright future". They will

never back down, but stand bravely on this land.
