Ignore you, the water of the Yellow River comes up from the sky and flows to the sea never to return.
Don't you see, the bright mirror in the high hall has sad white hair, and it looks like blue silk in the morning and turns to snow in the evening.
Don't you see, the water in the scientific research circle is turbid, but the clear current goes straight up to 90,000 miles.
Intention: Study hard and make progress every day
