Six thousand couples decided not to let the coronavirus deter them from celebrating their happy day. The multiple brides and grooms attended a massa wedding ceremony in South Korea’s Unification Church on Friday, in spite of the health sacre from the coronavirus in neighbouring China. The newlyweds were joined by 24,000 guests; some renewing their marriage vows and others watching friends and family tie the knot. The church seemed well prepared for such a large-scale event as staff handed out hand sanitizer and surgical masks to all attendees. They also checked the temperature of the couples.
