Ma Shi (1332- 1382), the filial queen of Ming Taizu, whose real name is unknown, is from Suzhou, the adopted daughter of Guo Zixing, the king of Chu Yang, and the original wife of Zhu Yuanzhang, the Ming Taizu.

1352 (in the 12th year), Ma married Zhu Yuanzhang, the general of the Red Scarf Army at that time. After marriage, Ma and Zhu Yuanzhang had deep feelings. In the years when Zhu Yuanzhang pacified the world and established the imperial industry, Ma shared joys and sorrows with him.

1368 (the first year of Hongwu) In the first month, Zhu Yuanzhang was founded in Yingtianfu (now Nanjing), with the country name Daming and Jianyuan Hongwu, and was crowned as the queen. Zhu Yuanzhang has always been very respectful and grateful to Ma Huanghou, and his suggestions are often carefully listened to and adopted. Zhu Yuanzhang tried to visit her relatives several times, but all of them were stopped by Ma Huanghou. Ma Huanghou always gently advised Zhu Yuanzhang to be gentle when he killed the hero.

The death of Ma Huanghou:

1382 (15th year of Hongwu) In April of the lunar calendar, Ma Huanghou suddenly fell ill. August, year of death 5 1. In September of the same year, she was buried in ming tomb, with posthumous title as the queen of filial piety. 1403 (the first year of Yongle) Honoring posthumous title: filial piety, filial piety, filial piety, filial piety, filial piety. 1538 (the 17th year of Jiajing) honored posthumous title: filial piety, filial piety, filial piety, filial piety, filial piety, filial piety, filial piety, filial piety.

After Ma Huanghou's death, Zhu Yuanzhang was very sad and never set up a queen.

It is said that women in Yuan Dynasty and early Ming Dynasty were all small feet, and women's big feet were a big taboo at that time. On the other hand, Ma Huanghou in Ming Taizu has unfettered big feet. The reason is that Ma Huanghou was deeply loved by his adoptive parents when he was young, and insisted on not binding his feet, so he developed a pair of heavenly feet, known as "Ma Dajiao".

After Zhu Yuanzhang became emperor, Ma Huanghou lived in the palace, but he felt powerless about his big feet. Whenever he meets guests, he always covers his feet with the hem of his clothes or skirt.

On one occasion, Ma Huanghou strolled through the streets of Jinling (now Nanjing) in a sedan chair. Suddenly, a strong wind blew and lifted a corner of the sedan chair curtain. Ma Huanghou's two big feet resting on the pedal were exposed in broad daylight. She quickly drew back her feet, but people had already seen them clearly!

So this new thing spread and caused a sensation in the whole capital. Because it was the horse that showed his feet, the word "showing his feet" has spread to today, so it is called "showing his feet" to expose disgraceful things that are inconvenient to disclose at present.
