Is your family member staying in Canada for more than 6 months AND has lived in one or more designated countries or territories for more than six months in the last year? Your family member's stay starts on the day they entered Canada and ends on the day they want to leave Canada.

如果呆了5个月的时候，想续6个月， 应该选yes 吧？
