I met someone today who told me her visa application to China was rejected on ''religious grounds''.
A typical, white teenager from London. I thought she was going to tell me she was Jehovah's Witness, had been to a rally for Tibet or something, but no - the only think she could think of was that her date of birth is 04-04-2004, the number 4 being too close in pronunciation to the word 'death' in Cantonese, and therefore the most unlucky number in China. She got into HK and Singapore ok. They probably did her a favor.
Oh man I never get visas ahead of time, get them at the embassy in the country you're leaving for entry in the next day or two. It's always easier away from central command.
