So you have things like resemblance, where something which resembles the physical world can be abstracted in a couple of different directions: abstracted from resemblance, but still retaining the complete meaning, or abstracted away from both resemblance and meaning towards the picture plan.
因此，你就有了表相， 也就是说代表现实世界的事物， 可以被不同的方式抽象化： 将表相抽象化， 但仍保留完全的含义， 或者将表相和含义两者都抽象化，趋于图形化。
