Where is the easiest place to renew my Chinese Visa

Hello,
I was wondering if you could help me with a PRC entry permit requirement for British. I am currently in China and my L type is about to end in few weeks. It is possible to obtain a PRC entry permit in Malaysia for at least 90 days double entries or 60 days entries. If not where is the easiest place apart from back home (UK) i could renew it please.

Many thanks
Solange
