Emergency workers dig through the rubble in a desperate search for survivors in a six-floor residential building in Ningbo, Zhejiang province, that collapsed on Sunday. Three people were found in the rubble; one was removed but later died in the hospital. Two people remain trapped. On Sunday morning, cracks started to appear in the walls of the building, which was built in 1989, forcing authorities to evacuate residents. Photo by Zhang Jia / for China Daily
