Can lawyer Wang be referred to as lawyer Wang for short?

Of course.

In daily life, people add "Fa" to a lawyer's surname, which is a common way to show respect and gratitude to lawyers. Lawyer Wang agrees or accepts this abbreviation, which can be abbreviated as "Wang Fa". This abbreviation is more common in oral communication or informal occasions. In formal occasions or official documents, the complete professional title "Mr. Wang" or "Ms. Wang" should be used.
