His first doctoral graduate subsequently received support from the NSFC Excellent Young Scientists Fund. Seven doctoral graduates received outstanding doctoral dissertation awards from professional societies: two from the Chinese Institute of Electronics, one from the China Institute of Communications, one from the Chinese Society for Electronics Education, and three from the Chinese Society for Optical Engineering. One master's student received the Outstanding Master's Thesis Award from the Chinese Institute of Electronics, and one doctoral student received the Beijing Outstanding Doctoral Dissertation Award. Four students received Peking University's Outstanding Doctoral or Master's Thesis Awards. One received the Tingye Li Memorial Scholarship, named in honor of the "Father of WDM" and awarded to only three recipients worldwide, and four were named National Microwave Photonics Rising Stars, an honor awarded to six recipients nationwide each year.
He has mentored 19 postdoctoral researchers, nine of whom have completed their appointments.
