I am marring a divorced Chinese lady. What are, if any differences in the 1st and 2nd marriage?

There is no big difference as long as you love each other. But I wanna tell you something: I am from a town in north China. The customs is that couples of the 1st marriage hold their wedding ceremonies at noon. While if for 2nd marriage, there won't be grand wedding and a simple ceremony is held in the afternoon only.
