How to see whether the patent is authorized?

Utility model and appearance patent can only be found after authorization. An invention patent is authorized if it can find an authorized description, but it is not authorized if it only has a public description. In addition, the invention patent is an authorization announcement document and has been authorized. Note that it is an "authorization announcement" rather than an "open". Because the invention patent is first "published" and then examined, and then "announced" after examination.
