Recently, I had been watching some Taiwanese serials, like Taiwan Tornado, to learn more about Hokien as spoken by the Taiwanese, and at the same time know more about their culture and beliefs which are mainly common to us.
One of the things I noticed which I find familiar with, is the strong filial piety shown by family members. This is despite the almost constant arguments among family members and those related in one way or other. During arguments, each will call the other by his or her full names! Eg. 'Huan Zhilong!...' and the response, 'Ang Bee Hua!...' Incidentally, Cheng hates to be called by her Mandarin name, 'Wang Cheng Wen', because that was how she was scolded by her mum when young! Must be really effective in showing one's displeasure.
Another common aspect of Taiwanese culture (uncommon here) is the act of kneeling to show one's apology. It is common to say 'Seet lay' while doing so, followed by 'heebang … guanliong.' which means, 'Sorry, hope for your forgiveness.' I don't think there is any other culture which practises kneeling so much in showing one's sincerity (though might be put on by pressure under the circumstances) in an apology. In Taiwan Tornado, even the Chairman of a large corporation had to kneel as one of the conditions for sorting out his company's financial problems. Even a hardcore gang leader and killer too, when he was feeling remorseful of his past murders.
As for filial piety, there were instances of having to do so even at the altar of dead ancestors, for ceremony like wedding; formal adoption; or formal apology for past mistakes. I think Chinese triad gangs still practise some form of religious rites like mixing each other's blood and praying in front of the altar of gods to show full commitment to each other like blood brothers and to their common cause. Filial piety, though scarcely practised in modern Chinese families, could still be found in Taiwan, according to the following report...
