Hursty I actually have a mate called Dan Wang, but he lives in Liverpool and is a primary school teacher.
Bang into prog mind you, but not a DJ.
Wang is by far the most common Chinese surname - more common than Smith is in the Anglosphere.
Dan is very easy for Chinese to pronounce - they struggle with long words composed of multiple phonemes, so often choose names like ‘Dan’, ‘May’, ‘Anna’ for their ‘Western name’. No surprise that there are a few Dan Wangs. Hope this helps.
