The classic lines and quotations of "Black Ice" are:

1. A Cicero philosopher said that everything in the world is written on the face, and you have to rely on your face to lie. But the eyes are traitors to the soul.

2. An ant nest was discovered by you, and the ant king was eliminated. But as long as there are a few ants left, a new ant colony will be formed immediately and a new ant king will be elected. Therefore, we are not destroying the ant nest, but removing the cancer. All the lymph and Qin Run related to it must be cleared away!

3. People are a multivariate complex variable function. If you stand the test today, you may rebel tomorrow. Today you are political allies, but tomorrow you may become enemies on the battlefield.

4. Usually a real smile can only last between two-thirds and three seconds, while a fake smile lasts particularly long.

5. When people look forward, it seems to be full of chance, but when it comes to summing up, looking back, everything is actually prescribed.
