Why did the ancient emperor choose the champion as his son-in-law?

All previous dynasties did not have the habit of recruiting the top scholar as Xu. Many literary works and plays greatly exaggerate the anecdote of "Ma Xu won the first prize". It seems that the first prize is Ma Xu's first choice. As a matter of fact, among more than 600 top scholars with famous surnames and deeds in past dynasties, there is only one real top scholar, and that is Ma Xu.

In the second year of Huichang, Tang Wuzong (842), Zheng Hao, a native of Xingyang, Henan Province, was the first scholar of Renxuke. The handsome young champion was taken away by Emperor Xuanzong of the Tang Dynasty. He wanted to betroth his beloved daughter Princess Wanshou to Zheng Hao as his husband. So Zaifu Bai Minzhong tried to sell good things. Originally, Zheng Hao had an engagement, and after winning the first prize, she planned to marry the daughter of Lujia, but Bai Min put in a thick stick.

Emperor Xuanzong of the Tang Dynasty personally married the princess, worshipped him as a captain of Xu, and was promoted to the position of Sheren of Zhongshu and Assistant Minister of Rites. Although Xuanzong paid special attention to him, he was always unhappy, and the two were not happy after marriage, although he missed Lu's daughter very much in his heart and could not tell Xuanzong and the princess. I have to vent my anger on the matchmaker Bai Min, and I will give Bai Min a hard time whenever I have the chance.

On one occasion, Bai Minzhong complained to Xuanzong. Xuanzong opened a big box and showed it to him, saying, "These are all the memorials of Zheng Hao impeaching you. I know the reason, so I pressed them down. "
