Going to Chengdu, China

Hello, What do I need to get to Chengdu China, I'm from Philippines. As what I have read, i can apply a tourist visa for mainland china here in hongkong and now that I'm here in HK, the chinese consulate didn't accept my application cause i would need to get it from my home country. Either way - I'm just travelling to see my best friend which is swedish in Chengdu as he has given me his address.. What can you advise on this? I'm currently in Hong Kong..
