唐僧洗头爱飘柔观音洗澡用大宝
[táng sēng xĭ tóu ài piāo róu guān yīn xĭ zăo yòng dà băo]
This is a humorous mix of modern products with classic Chinese characters from the famous ancient novel 'Journey to the West.' Tang Monk (a monk in the story) prefers the popular shampoo Pantene, while Guanyin (Goddess of Mercy) uses Dashibao soap for bathing. It implies an amusing mismatch of ancient figures enjoying modern life comforts.
