My great grandfather was a Party member (党员). He was born in the 1930s. As one of the first geologists (地质学家) during the founding (建立) of New China, he worked very hard with his teammates. They discovered many mineral resources (矿产资源), such as iron (铁), gold, and coal (煤炭). Their discoveries were important for New China. My great grandfather was adventurous and traveled all over the country. He is my role model (榜样).
