While recovering at home, she observed that the swallow couple were about to have babies! Yiyi was worried that the swallow couple could not finish making their nest before incubating the swallow babies. Having discussed with her friends, they decided to look for a new house for the swallows. Finally, Yiyi and her friend inserted an old shoe of her father's into a gap in the iron stand of the rooftop, giving the swallow couple a firm new home, so that they could concentrate on incubating the swallow babies.
