The Suzhou-style mooncake originated in the Tang Dynasty and flourished in the Song Dynasty, lesser-known compared to the more famous and widely spread Cantonese-style mooncake, the Suzhou-style mooncake is even unknown in many regions.
Take Jiang Feng, for example, before attending university, he only knew of Cantonese-style mooncakes and was completely unaware that there are in fact many different types of mooncakes; he always thought there was only one kind: the Cantonese-style mooncake.
The only difference being whether they contained egg yolks or not.
Then there's Wang Hao, a local from Alan City, where Suzhou-style mooncakes weren't sold in earlier years, only in recent years did they become popular in Alan City.
When he first saw a Suzhou-style mooncake, he insisted it was just a baked sesame cake and even argued with the shop owner, ultimately getting himself blacklisted from the store.
