Homemade lasagna

Tomorrow is the 15th night of the month, and we've got some lasagna for the weekend. Every year on this day, we eat the night as usual. When I was a kid, my mom wrapped up our white beryllies with our own rice powder; that's the kind of thing with no pie. As the economy continues to develop, there are no more platinum mills in the region, so we have to go to the grain station and buy a bag of platinum powder; then from the planned economy to the market economy, the grain station is gone, and the supermarkets appear; and we get lazy and we enjoy it, and every single night, we don't think about wrapping up our own soup and bringing it back from the supermarket. But since last year, I've been doing it myself. Because there is no stone grinding powder, only a bag of rice powder can be bought. It's different from when you're a child; it's not a greasy black sessa; it's a light potato pie; it's a little bit of sugar that can be eaten directly, softly, chewed so hard that it feels better than a machine pack
