The water shield is a first-class protected aquatic plant in China. It requires a highly qualified environment with zero-polluted water and acidic soil. In Chongqing's Shizhu Tujia Autonomous County, many villagers grow this precious plant owing to the pure environment, allowing them to increase their income and even be lifted out of poverty. The little plant has become a local pillar industry as the local government implements targeted assistance to help farmers improve their living standards. 

Reporter Guo Tianqi will take you to pick water shields and visit local factories to learn how a good industry brings people happier lives.
