Yes,
I know Hangzhou is a dry town, however my C1 licence was issued here and I have residence address registered here. If this is a problem (I hope not) I'll just move my residence outside just for the driving licence purposes.

While this may be a "regulated" situation for our chinese brothers I'm not sure my case is contemplated for the laowai.

In fact I know that if a chinese wanted to do this he would need to re-do written exam AND driving, I of course hold a valid european AB driving licence and a C1 driving licence making my case different.

Make me re-do the written paper only wouldn't make any sense according to me... but yet it wouldn't surprise me at all, Chinese laws and regulations never do much sense to a laowai.

So far I've asked help to one person at work which is "asking a friend" with astonishment in her face... I could already read in her face "these laowai are real strange, why would he want to drive a motorbike anyways, motorbikes are for countryside people!"
