Wei Zheng: "If these large tracts of potatoes, sweet potatoes, corns, and advanced workshops can be promoted in the Tang Dynasty, it will be of great benefit!" Li Jing: "There are countless disciples in Zhongnan Mountain, and each of them is talented in both civil and military skills. No one in the world can compare with the Immortal Master in terms of teaching!" Li Shimin: "You don't have to be polite whichever Princess of the Tang Dynasty you like.
