We give a much simpler and unified proof about the limits of two towers of function fields over finite fields, avoiding all technical difficulties.One tower is over square finite fields and it attains the Drinfeld-Vladut upper bound, and the other is over the finite field with eight elements and it attains Zink's lower bound.
