My sister called many times from the south to ask my father and mother to stay with her for a period of time. After a period of preparation, my wife and I found an excuse to leave the children in my mother-in-law’s home and entrusted them to my mother-in-law and their aunt to help take care of them. One morning at the end of September, four of us boarded the plane to the south. After a plane change flight, we arrived in the city where our sister lived in the evening. When we got off the plane, we saw our sister standing at the exit of the airport waiting for us.
