Because the city walls are high and the temples are towering, the palaces are full of ancient trees, which shows that the city walls are high and the temples are strict, and the ancient stone tablets are in the forest. The palace is as deep as the sea. Does the emperor make people look forward to it? It is quite touching to board Tianjie, and the archway is like pine and cypress. Therefore, the poem describing the pine and cypress on the wall at night is: the wall is high and the temple is towering, and there are many ancient trees in the palace.
Pine and cypress are widely distributed in southern North China and eastern China, and are often used as ornamental trees in gardens.
