A: "And you came from---?" B: "From Lowood school." A: "Ah! A charitable concern. How long were you there?" B: "Eight years." A: "Eight years! You must have a strong hold on life! I would have thought that time in such a place would have ruined anybody's health!" Based on the contents given in this dialogue, when A said "You must have a strong hold on life", it would mean that B had endured all suffering during the time he/she spent in that school, which was thought to be very tough to a general individual. For example, a military boarding school may contain such characteristics in order to train its members. === I wish you a good day.／祝　是日安好。
