There's a sign with flashing  lights in the hotel where I am staying that says "Welcome to  Sheng Kun".  Speculation on why as sign in  Bujumbura  would  say that yielded  no  clear  answer. I  asked on of the waiters but he  also  didn't  know. My guess is that either a) the sign  was there before and had been  programmed  by the previous owners,  or b) the hotel bought the  sign because they liked the fact that it was flashing and  also said  "Welcome".
