return to soup with dried bean curd.

In old Shanghai, there was a vendor who specialized in selling dried tofu and tea eggs. If it is not sold out that day, they will take the dried tofu out to dry and sell it the next day. So I used the metaphor of "returning soup and dried tofu" to return to my old job.

The newly-opened dried bean curd should correspond to the "soup-returning dried bean curd".
