Important rules have been created that relate to the nature of the lines, their lengths and combinations of materials, the use of or (straw bundles), etc. Editing in that style can only be done through regular and long-term practice. The main axis, often the branch, is predominantly perpendicular, often the axis is formed by pine branches and is the most distinctive element of the arrangement.
