Hubei high school students take invention gold in US

In June three students from the same high school in Hubei province each won a gold medal at the Invention and New Product Exposition in Pittsburgh, one of the largest invention trade shows in the United States.

One of the budding Chinese inventors from Wujiashan High School in Wuhan city is Wang Yujie, a 10th-grade student who won gold at the international expo for her invention that enables automatic control of oxygen in fish ponds.

Her childhood was spent in the coastal province Zhejiang and she now lives in an area of Wuhan abundant in rivers, where Wang heard many stories of fish dying from the lack of oxygen at night.
