Yang (surname) - The "Four Wisdoms"

The "Four Wisdoms"

Some branches of the Yang clan (in particular the Hongnong branch) refer to themselves as "Yang of the Hall of Four Wisdoms". The "Hall of Four Wisdoms" refers to a story concerning Yang Zhen, an official of the Eastern Han Dynasty (206 BC - 220 AD), known for his erudition as well as moral character. When a man named Wang Mi visited Yang Zhen at night and attempted to bribe him 10 catties of gold, Yang rejected the gift. Wang Mi persevered, saying that nobody would know. Yang Zhen famously retorted "Heaven knows, Earth knows, you know and I know. How can you say that nobody would know?" Descendents of Yang Zhen adopted the "four wisdoms", or "Si Zhi" as the title of their clan hall. Some Yang family clan halls in various parts of China still carry this name.
