Since we're going to practice Crab Yellow Sauce, naturally we have to use Cao Guixiang's most skilled thickening technique.
Zang Liang secretly gave this thickening technique a name, called "Big Circle Thickening," meaning that the technique is very flamboyant, requiring a big circle motion to thicken.
Qin Huai understood Zang Liang's intention and kindly expressed to him that the name was good but let's not use it again. Let's just forget about "Big Circle Thickening."
At this point, someone might ask, hasn't Qin Huai been stir-frying yam at Cao Guixiang's house for many days? Did he practice Cao Guixiang's unique thickening method?
Yes, he did.
These days, it seemed like Qin Huai was stir-frying yam and brushing up on his knife skills and fire control skill level. Of course, he was indeed doing those things, but essentially, he was still learning and practicing thickening.
Thickening is not knife skills or fire control; this basic skill of thickening is a technique.
