Among them, the image of the herringbone arch has also developed from the initial stiffness and straightness to the beautiful curved foot herringbone arch. As for the roof, a new style of warping angle appeared in the murals of the Eastern Jin Dynasty, which is called warping angle. And with the lifting and folding, the huge roof looks light and lively. For example, the architectural image of the Northern Wei Dynasty in Dunhuang murals, the tall buildings, the slightly childish roof curve and the owl's tail all reflect the architectural style at that time.
