According to Wan Lei, "Statistics showed that the Japanese destroyed 220 mosques and killed countless Hui people by April 1941." After the Rape of Nanking mosques in Nanjing were found to be filled with dead bodies.They also followed a policy of economic oppression which involved the destruction of mosques and Hui communities and made many Hui jobless and homeless.
