Why is Yu Yao the only one who smells like cattle?

Because the smell of cattle in Yuyao is very local.

1. In Yuyao, there are cow-flavored restaurants everywhere, and umbrella bags, cow eggs and cow heart tubes are unheard of; Umbrella bag is a local dialect, which is actually the fourth stomach of cattle. Compared with the common hairy belly and tripe, the umbrella bag is softer and more elastic, and there are not so many spikes, which is rare elsewhere.

2. Many Niu Wei restaurants in Yuyao are old restaurants handed down from generation to generation, with special tastes, which are difficult to replicate elsewhere.
