[1.16.5] How could I display HP at living entity head?

How could I display HP at living entity head?

I want to display a HP bar at entity head, kind of a floating rectangle.  But I have no idea what method I could use or what class I should concern.  

Could some experienced modders give me some guidance? Please🙏🙏🙏

Use EntityRenderersEvent.AddLayers to add a RenderLayer to the renderer of the entity type(s) you want to change.

Then in your RenderLayer.render() draw your stuff. You get passed a reference to the entity so you can access whatever data you want.
