These are LOGOs I designed in the past. For the lab, the school, the team, and myself. Most of them are not adopted 😮‍💨, just for fun😁.

This is the LOGO I designed for myself, based on my name initial.
Those three are what I designed for the labs and school. Unfortunately, beaten by other candidates.
The LOGO I designed for the Zhejiang University tennis team is adopted and made a jacket for our team.
