Where can I buy delicious thousand-layer cakes in Taiyuan?

Last week, I tasted Melaleuca cake for the first time on my good friend's birthday. I've heard of it before, and I have a chance to eat it this time. I ate a durian and felt quite good! It's better than just eating durian. The skin is very fragrant. My friend is a foodie, saying that he has tasted several brands of this kind of Melaleuca cake, but Vivian's is more authentic. You can try!
