Mr Li Bo is a little younger than Mr Kang Zhen (born in Li Bo 1972 and Kang Zhen 1970). Both of them graduated from Normal University, and Kang Zhen graduated earlier than Li Bo. Li Bo himself is a teacher of Nanjing Normal University, and Kang Zhen has also studied and worked in Nanjing Normal University. This title can be said to be very accurate.
