Born in California, United States, he holds a bachelor's degree in mathematics from the University of California, Los Angeles and a doctorate in psychology from the California School of Professional Psychology, majoring in college teachers, but because of the "English only" turmoil in Monterey Park, where the Chinese population lived more than twenty years ago, he began his political career by coordinating with the mainstream community, and later became an elected official, serving as a school district education commissioner, a Montene City councilor, a California state congressman, and finally a member of the California Tax Authority. Zhao once said he was proud of his ethnic integration and being Chinese, but he also voted against the Chinese-friendly STEM green card proposal because it was unfair to Mexicans.
