Question about Individual Tourist Visa for Sri Lankan in Malaysia

Hi, I am presently working in Malaysia and I bought my air ticket to China, Hotel bookings and had all the requirements to obtain chinese visa from here. However, when I went to the embassy they said they give visa only one month before travel. The problem is, we will be returning to Sri Lanka in June permanently and so will not be around to get the visa from here. Do you think there is any chance of getting it if we present our case?
