My Hong Kong immigrant account was cancelled. Can my unsuccessful daughter be the head of the household?

You can be the head of the family. According to the Notice on Further Strengthening and Standardizing Household Administration, Regulations on Identity Cards of registered permanent residence and Residents, Regulations on Police Work of Guangdong Public Security Organs and other relevant requirements, in principle, minors can't be heads of households and can't open separate accounts. If it is necessary to open a separate account due to special circumstances, the actual guardian may apply to the public security organ.
