Why is Toona sinensis called the king of trees?

This is a folk legend: at the end of the Western Han Dynasty, the consorts held power, Wang Mang made up the throne, and Liu Xiu was forced to flee. He was displaced and did not have enough to eat along the way, and experienced many ups and downs. One day, he was hungry and cold, but fortunately he met a mulberry tree, so he saved his name and life. Later, Liu Xiu proclaimed himself emperor and established the Eastern Han Dynasty. Because of Mulberry's saving his life, he wrote a calligraphy title. Just because the confused minister didn't know mulberry trees, he hung the gold medal on the Toona sinensis by mistake. Although Zhang Guan Dai Li, Toona sinensis is the king, it has spread among the people.
