We all know why Xiao Hei had to threaten the fat boss coz Wowo is nothing like Cinian nor Qu Cheng. All Wowo knows how to do is to eat and waste his allowance lol. Maybe he has some of Cinian's sense of business but I don't think he is nearly as shrewd nor tactical as when Cinian at the same age.
And it's fine coz Wowo has his parents and his younger sibling who have more potentials and brains than him lol. It seems that Wowo serves only as someone to be coddled in the family.
