Burmese-Chinese brothers Aw Boon Haw and Aw Boon Par, the developers of Tiger Balm, opened Haw Par Villa in 1937 in Singapore, where statues and dioramas were commissioned to teach traditional Chinese values. Today, the site contains over 150 giant dioramas depicting scenes from Chinese Literature, folklore, legends, history, philosophy and statuary of key Chinese religions, Taoism, Buddhism and Confucianism. The best-known attraction in Haw Par Villa is the Ten Courts of Hell, which features gruesome depictions of Hell in Chinese mythology and in Buddhism. Other major attractions include dioramas of scenes from Journey to the West, Fengshen Bang, The Twenty-four Filial Exemplars and the 12 animals in the Chinese zodiac. The park was a major local attraction During the 1970s and 1980s; it is estimated that the park then welcomed at least 1 million annual visitors, and is considered as part of Singapore's cultural heritage.
