Lin Ershuan didn't expect Jin Lingling to turn the tables on him again, and he quickly retorted, "No, no, this isn't my handiwork. Miss, if you don't believe me, you are fully welcome to come and see for yourself. This, and this, the wooden pegs of these two wheels are completely different. You can tell at a glance which was made by me and which was not."
It's the same with carpenters, as it is with anyone else who works with their hands; they can recognize their own work no matter how much time has passed. The Jin family runs a vinegar brewery and couldn't possibly fail to recognize their own vinegar if they tasted it elsewhere. What Lin Ershuan explained was precisely this concept.
