Some commonly used MyBatis tags include:

1. select: used to perform database query operations.
2. insert: used for executing database insertion operations.
3. update: used to carry out database update operations.
4. delete: used to perform database deletion operations.
5. resultType: specifies the type of the returned results.
6. resultMap: used for customizing result mapping rules.
7. parameterType: used to specify the type of incoming parameters.
8. foreach is used to iterate over parameters of collection types.

The method of handling special characters:

1. Angle brackets (<) and greater than signs (>): You can handle them using escape characters, for example, replacing “<" with "<" and ">” with “>”.
2. Single quotes (”) and double quotes (“”): can be escaped using a backslash, for example replacing a single quote with “‘ “and a double quote with “\””.
3. Special characters (such as &, <, >, ‘, “) are illegal in XML documents and can be replaced with entity references. For example, ‘&’ can be replaced with ‘&’, ‘<' can be replaced with '<', '>‘ can be replaced with ‘>’, single quotes can be replaced with “‘”, and double quotes can be replaced with “”.
