Tourism Visa application for Lebanese Student in Singapore

Hello I am a Lebanese citizen who will be residing in Singapore for the last four months of my MBA program at INSEAD university. I want to apply to the Chinese visa 6-months before I go to Singapore because I am sure we are going to embark on a student trip to China while we are at university. Yet, I am not sure of the dates of this travel. Can I still process the visa without having a flight and a hotel booking (I can show documents of money availability to book flights/hotel, but I don't want to book and cancel later in case of date changes)?

Thanks,
