I applied for a double entry 6 month visa but didn't realise one stay had to be no more than 90 days. Is it possible to stay for 93 days?

I am arriving in China from Switzerland on October 7th and leaving for a one week holiday in the Philippines via Hong Kong on January 7th. After that I want to return to China for a few days and then leave to go back to Switzerland on January 23rd. I thought a double entry 6 month visa would be fine but now I am told that each stay must not be more than 90 days. In fact October 7th to January 7th is 93 days. What is the best way to get round the visa problem?
