Actually under the Solicitor Practice Rule of the Legal Practitioner Ordinance, a solicitor may advertise. But he may not say he is an expert in certain areas. He can only say he certain years of experience in a particular area(s). Also a solicitor may not advertise in a way that brings the profession into disrepute. That's where Paul Tse 謝偉俊 is in breach of the solicitor practice rule by letting his almost "naked photo" appear in a magazine years ago.
