 By the early 1930s , Wijnhamer , known as Pah Wongso , was recognised in West Java for his promotion of social causes . These included promoting monogamy and faith in western medicine , as well as combating gambling and the use of opium and alcohol . In conveying his messages he often used the Sundanese wayang golek ( a form of shadow puppets ) , as the local people were generally unable to read . He was able to speak Dutch , Malay , and Javanese fluently , and had some command of Chinese and Japanese . This social work was funded predominantly from Pah Wongso 's day job , selling fried peanuts ( <unk> goreng ) .
