But it probably should have been. After 10 years of being married, my hus- band and I were definitely ready to have a child, but we were still worried about whether we would really have the time and money to bring up a child. And for me, the pregnancy process itself seemed daunt- ing - how would l change？ Would I ever go back to ＂normal？＂展开更多
An 18-month-old boy who was playing on a hill fell into a crevice of a hill about 20 centimeters wide and about 40 meters deep. He was finally rescued by a 12-year-old boy. This is a true story.
