-The Subclass relationships were expected to be transitive, right? (i.e., if `A` is a subclass of `B`, and `B` is a subclass of `C`, the `A` _should_ a subclass of `C`)
+子类关系应该是可传递的, 对吧? (即, 如果 `A` 是 `B` 的子类, `B` 是 `C` 的子类, 那么 `A` _应该_ 是 `C` 的子类.)
 
-#### 💡 Explanation:
+#### 💡 说明:
 
-* Subclass relationships are not necessarily transitive in Python. Anyone is allowed to define their own, arbitrary `__subclasscheck__` in a metaclass.
-* When `issubclass(cls, Hashable)` is called, it simply looks for non-Falsey "`__hash__`" method in `cls` or anything it inherits from.
-* Since `object` is hashable, but `list` is non-hashable, it breaks the transitivity relation.
-* More detailed explanation can be found [here](https://www.naftaliharris.com/blog/python-subclass-intransitivity/).
+* Python 中的子类关系并不一定是传递的. 任何人都可以在元类中随意定义 `__subclasscheck__`.
+* 当 `issubclass(cls, Hashable)` 被调用时, 它只是在 `cls` 中寻找 `__hash__` 方法或者从继承的父类中寻找 `__hash__` 方法.
+* 由于 `object` is 可散列的(hashable), 但是 `list` 是不可散列的, 所以它打破了这种传递关系.
