I think 10K is enough IF you have your healthcare and your flat rental shouldered by the company at the very least (i.e., if you're single). If you're up for the experience of working here, I believe you'll find a way to make ends meet, but make sure that you'll save enough money to buy your flight tickets.
You might want to consider if the 10K is post tax already.
I usually live frugally during my first couple of months, but after that, I can splurge a lot more when it comes to lifestyle (e.g., clubbing, dining out, shopping).
If you're not used to eating Chinese food (and I don't mean Chinese food in UK), your meal budget can be rather tough on your pocket. But if you don't have a sensitive stomach, I think you can easily adopt to the local food. Don't get me wrong, though. With 10K, you can manage to have a nice Western dinner at least once or twice a week.
Here's a basic LOCAL budget sample:
Meals 30 RMB/day (bfast, lunch & dinner)
Transportation 10/day (or less 2-way on metro)
Bills & Utilities 500/month
With this you'll still have around 8K RMB that you can split for clubbing, dining out, shopping, and savings. To me, 8K is more than enough.
I believe it's a matter of perspective.
