Great Tang: Starting by Slaying a Dragon

In the first year of Zhenguan (627), Li Shimin ascended the throne and appointed Wei Zheng as Shangshu Zuocheng. Li Shimin was determined to establish a prosperous age, so he summoned Wei Zheng to his bed many times to inquire about the gains and losses. Wei Zheng spoke frankly and gave advice on more than 200 matters, which Li Shimin fully accepted.
