Emperor Taizong had a famous horse named Lion Luo, which was a gift from the western countries. Emperor Taizong liked it wild and heavy, but suffered from it not being tamed. One day, Emperor Taizong summoned several civil and military ministers to the royal stable and asked them, "Who can handle such a good horse?" At this time, Wu Meiniang walked up to Emperor Taizong and bowed down and said, "Both men and women can do it." Emperor Taizong asked her what to use to tame fierce horses. Wu Meiniang replied, "As long as your majesty gives your male and female servants three things, a iron whip, a hammer and a dagger. Male and female servants will be whipped with iron whip first. If it is not tamed, they will hammer it. If it is not tamed, the male and female servants will cut its throat with a dagger! " At Mei Niang's voice, Emperor Taizong clapped his hands and praised Wu Meiniang: "You have courage! Have ambition! " .
