Rescuers check the site of a cave-in on Lyucuo Road where a Line 2 subway station is under construction in Xiamen, East China's Fujian province, on Dec 12, 2019. An area totaling 500 square meters collapsed and water pipes broke at about 9:50 pm Thursday. Two cars slipped into the deep space but no one was trapped and the people in the vehicles escaped safely. [Photo by Ye Yiheng/chinadaily.com.cn]
