All better grade Kason racquets have the signature of Master Tang, also known as the "Thing", who is an advisor to Kason.

Those pics are from the Chinese national tournament, where the pros, playing for their provincial teams, wear the logos of their local sponsors. Internationally, they're all sponsored by yonex, but at the provincial level they play for different companies.
