Applicants for a business visa require an invitation letter, but visit visas do not. http://www.chinese-embassy.org.uk/eng/visa/rcgadq/t519931.htm Your family will be accompanying you as visitors, therefore IMHO itβs not necessary for the inviting company to include their names in the invitation letter, unless the company is covering all or part of their expenses. All visitors to HK who do not qualify for visa-free entry need to apply in their own right https://www.immd.gov.hk/eng/services/visas/visit-transit/visit-visa-entry-permit.html
