It is a coincidence that "the name comes with its own official position". Zongtang is the name, and Zhongtang is the official position (the Qing Dynasty's nickname, elegant title or honorific title for the first-rank cabinet bachelor). The ancients were very particular about it. It was disrespectful to call someone by his first name. Because Zhongtang is the same as Zongtang, and there is a second-class marquis on Zuo, so Zuo's colleagues called Zuo "Zuo Xiang", "Zuo Hou Xiang", "Jue Shuai" and so on.
