Let's think of a personalized name for mutton soup.

If you are the kind handed down from home, I suggest using Lao Wang's family and Lao Li's family. This "old X's mutton soup" has a sense of historical precipitation.

If you want to open that novel mutton soup kitchen, you might as well name it after its geographical location to facilitate word of mouth, such as "Xi 'an mutton soup kitchen" and "Qin Zhiwei mutton soup kitchen".
