Why is the alkaline water knot in this shape

The reason for the twisted knot style is to maximize the contact area of the bread surface with the lye water. A perfect lye knot with a smooth and shiny crust, showing a charming reddish brown color, a bite will feel the special aroma of lye water, followed by the saltiness of sea salt coming from the tongue, and the aroma of wheat is released in chewing, making it an extremely characterful bread.
