Wen Yang was a famous general of Shu Han during the Three Kingdoms period and was known as the first war god in the later period of the Three Kingdoms period. He led his troops to defeat Cao Wei's army many times and performed well in the Battle of Red Cliff, making great contributions to the victory of Shu Han. However, Wen Yang had also encountered setbacks and misfortune in history. In the last years of Cao Wei, due to political corruption and internal strife, his family and troops were killed by Cao Wei officials, causing him to suffer the tragic disaster of extermination of three tribes. The reason why Wen Yang's three clans were exterminated might have something to do with his position and status at that time. As a general of Shu Han, his status was relatively high, and he might also be suspected and ostracized by Cao Wei officials. In addition, due to the war between Shu Han and Cao Wei, Wen Yang might be regarded as one of Cao Wei's hostile forces, which also led to his encounter.
