I really think Max needs to learn how to dress in front of public.
I mean he doesn't need to wear a suit, but a collared and pair of trousers is preferable.
I asked a lot of people here in China and it's definitely not required. In some of the pictures I will post after I'm back in Germany, you see many big guys with shorts and a t-shirt. It just doesn't matter in Beijing at 35°C.
Also, I'm not a business man. I'm a normal startup guy who loves to build products and speak to people. That's just how I'm and I think a lot of people have a lot of fun with me here in China. What matters is the idea behind Lisk, not how I dress.
Hey Max, the guy who built the largest company in the world (Apple) wasn't especially well dressed neither.
Who give a shit about dress code? Keep focusing on what you love the most: building products and speaking to people.
