Ha! I have been following his Chinese channel for a while. Didn't know he also has an English channel. IMO, brother needs to work on his Chinese accent a bit. (I can say that as I am a Chinese, too)
As an amateur angler, He is knowledgeable about bass fishing, also has some interesting insights and perspectives regarding reels and rods, as he holds a Ph.D in chemistry. He is a super fan of Shimano and Megabass mostly, not many other brands, but like you said, he is a true fan.
