control

The source is difficult to control.

(Ice Source)

The relationship between the sun and the moon is always constant.

How can you know that the leaves turn yellow and fall in summer?

Time controls the non-proliferation of personnel and the rise and fall of things.

As the river passes, the earth loses its vitality and the sea water boils.

源难控

(冰源)

日暖月伴永恒定，

怎知盛夏叶黄飞!

时控人非物兴衰，

江逝地失海枯沸。
