Yang Feng
After they returned to Luoyang with Emperor Xian, internal conflict broke out between the generals Han Xian and Dong Cheng, who were among those who escorted the emperor back to Luoyang. During this time, Xu Huang persuaded Yang Feng to summon the warlord Cao Cao to Luoyang to help them deal with the crisis and protect the emperor. In early 196, Cao Cao and his troops showed up in Luoyang and fetched Emperor Xian to their base in Xu (許; present-day Xuchang, Henan), which became the new Han imperial capital. Yang Feng initially wanted to heed Xu Huang's suggestion and join Cao Cao, but ultimately refused and went his own way. Xu Huang followed him.
