This association has strong roots in China's agricultural society, where regular rainfall and balanced water supply were critical for crops.

这种协会在中国农业社会有着深厚的根基，在中国，定期降雨和平衡的供水对农作物至关重要。

The construction of this project is another step forward for China's west-to-east power transmission program that balances the country's electricity supply and demand in different regions.

该项目的建设是我国西电东送平衡全国区域电力供需的又一重要举措。
