+## Notice for inheritance
+
+`go-hessian2` supports inheritance struct, but the following situations should be avoided.
+
++ **Avoid fields with the same name in multiple parent struct**
+
+The following struct `C` have inherited field `Name`(default from the first parent), 
+but it's confused in logic.
+
+```go
+type A struct { Name string }
+type B struct { Name string }
+type C struct {
+	A
+	B
+}
+```
+
++ **Avoid inheritance for a pointer of struct**
+
+The following definition is valid for golang syntax, 
+but the parent will be nil when create a new Dog, like `dog := Dog{}`, 
+which will not happen in java inheritance, 
+and is also not supported by `go-hessian2`.
+
+```go
+type Dog struct {
+	*Animal
+}
+```
