“Gǔzǎo wèi” (old-school flavor) is a phrase you see more in Hong Kong and Taiwan — roughly means “ancestral recipe.” In northern mainland China, “old-school flavor cake” would probably just be called “traditional sponge cake,” though honestly it’s almost indistinguishable from chiffon cake at this point.

First time making this thing, and it turned out a bit better than I expected.
