What do you mean by asking what is in the world? Is it bittern tofu? Everything has its vanquisher.

It means that emotional things are like ordering brine tofu. Soak beans, grind them into soybean milk, and then boil them. Add a small amount of salt water, and soybean milk will condense into tofu. No matter how tough a person is, no matter how tough he is, once he meets someone he really likes, it's like everything has its vanquisher in front of him and obediently surrenders.
