All right, a quick update.

After kissing goodbye to my car driving licence at the main traffic bureau, back to the local traffic bureau to apply for a new licence.
Health check VERY nominal, they gave me a book of questions and my exam date is... END OF JUNE!!!! I expected a couple of weeks of illegal driving and now I'm facing at over two months...
My fixer is working on this "small" issue.

I didn't download anything yet, but they kindly gave me for free a book of about 250 pages with 6 questions per page average... I'm already starting to regret all this effort as on the motorbike side, news so far are no good.

As it seems the JH600 can't be registered in Zhejiang, even on the name of a Chinese national. I'm not settling for a 250cc so maybe all this will be for nothing but a piece of paper.

On a positive note they gave me the application for C1D driving licence, so if will loose my job I can move to countryside and sell fruits on my moto-tricycle.
