13 Farmers Moved China

CCTV.com News: 13 farmers from Yutian Country, Tangshan City, Hebei Province have formed a rescue team to the snowstorm stricken areas in South China. On the Eve of the Spring Festival, driving a rented bus for Chenzhou, Hunan ,they joined the disaster relief team. On the spot of a Chenzhou’s emergency repair ,Song Zhiyong ,a farmer in Tangshan ,and also the group leader of the voluntary rescue team is working hard with 12 brothers in the village.

Song Zhiyong said that the idea of giving the support to the disaster area first accurred to them on Dec. 28 of the lunar year, when the celebration of the New Year was approaching. They planned to donate some money to Chenzhou there at the very beginning. However ,later ,they thought that was not enough and then they changed their mind.

“We should arrive at the front line, which is also a kind of comfort to the people there.” Song Zhiyong thought to himself.

When the journalists ask why they come to their rescue ,they said, “we have experienced the oversized earthquake before ,and at that time the people from all over China helped us. I think we also should try our best to help others in trouble and do what we could for them.”
