------ Solution --------------------
Website root directory \ phpcms \ templates \ default the template here is the default template. if you want to add a template, you only need to create your own template directory in the default directory of the same level, such as the website root directory \ phpcms \ templates \ my_templates as for style and js references in caches \ configs \ system. reference default templates and manuals for data calls that reflect templates in php
