A chained monkey in a costume performs in Depok, West Java, Indonesia, 30 January 2018. Monkey street performances or “Topeng Monyet” is a popular form of cheap entertainment in Indonesia, especially on the island of Java. During the topeng street performance a trainer issues commands by tugging on a chain tied around a monkey's neck, forcing it to carrying out tricks such as donning a mask or riding a toy motorcycle. In 2013 the Indonesian government banned Topeng Monyet in Jakarta but the ban has failed to stop the practice in other parts of the country. (Photo by Adi Weda/EPA/EFE)
