On 29 November 1887, following friction between the Ghee Hin and Hai San secret societies,[REF] a brothel skirmish in Papan escalated into a violent clash which became known as the "Papan Riots", the most serious Chinese secret society clash ever to take place in the Kinta district.
In early 1892, a large force from the Perak Sikhs was sent to Pahang to quell an uprising there.
