Heart cake

I've always wanted to learn, but I think it's very simple to look at Fong, but I think it's very difficult to actually do it. It took several failures to succeed, and I sum up the reasons. Good squares are very important, but I want a simple and easy-to-operate square. A video was then unwittingly visible online and felt very simple and very suitable for White. But the video doesn't say it's a couple of inches of Tiki's square, so I had to match it with my previous measure of the square. It's really very simple, but I'm putting out a recipe to make it clearer to everyone, so every step is very detailed, and hopefully it's going to help the white baker like me。
