I am a third-year CS master student of School of Electronics Engineering and Computer Science, Peking University (PKU). It’s my great honor to be here to learn from Prof. Zhouchen Lin and a lot of excellent lab-mates. Before this, I obtained my bachelor’s degree from University of Science & Technology of Beijing(USTB) and double degree in economics from National School of Development, Peking University (PKU) in 2017.
