After it is folded, it will be embossed. Experienced people use their fingers to press it down from above, then slightly reshape it and steam it on the drawer. The last step is slicing. Be careful not to cut with a knife, but use a clean rope. After cutting, you can see that each piece has a different pattern, which is not only delicious, but also a visual enjoyment.
