What is the ninth floor cake mountain to Kwai Wu?

The nine-story cake hill to Kwai Wu is made of rice surface layer by layer, and the method is the same as that of rice surface layer, that is, after steaming one layer of rice surface layer, it is not peeled off from the bottom of the pot, and another layer is steamed, and so on, until it reaches the required thickness. In earlier years, before Tanabata every year, every household had the custom of making nine layers of cakes, which were yellow and brown, full of Q-bombs, slightly sweet, slightly plant ash-flavored, sweet and fresh and unforgettable.
