+- For type definition, see [Type Systems in
Spec](../specification/xlang_serialization_spec.md#type-systems)
+- `int16_t[n]/vector<T>` indicates `int16_t[n]/vector<int16_t>`
+- The cross-language serialization is not stable, do not use it in your
production environment.

+# Type info(not implemented currently)
+
+Due to differences between type systems of languages, those types can't be
mapped one-to-one between languages.
+
+If a user sees one type has multiple fury types, for example, `long` in java
has type `int64/varint64/sliint64`, it
