The people who are old enough to engage in scientific research are Song Chaobei. This book tells the story of Professor Tang, the pillar of the country, a young plum dressed as a man in the literary age. Xiaoqing Mei Jiaojiao has a gentle and sweet voice, and there are many people chasing her, but she insists on hanging herself from a man's tree. When Professor Tang came over, the first thing he said was that the man was dead or alive, and his father's leg was going to be broken. Then, Professor Tang gave up the male master decisively and raised his hand to swear: study hard and serve the motherland.
