In 2017, Wu Linshou and Zhao Xiangying, a couple who studied in France, returned to their hometown of Wuyang, a seaside town in Zhanjiang, to renovate their ancestral home for their parents, for a family of 3 generations, 10 people living together. During the "hottest summer in history", the two elderly people did not use air conditioning at all, instead they relied on patios, courtyards, roofs to achieve natural cooling. At the end of July, YIT came to Wuyang Town to visit the family of 10.
