How must a tourist in Singapore apply for a China visa?

Hi, I am an EP holder living in Singapore and am planning a trip to Beijing and Shanghai. Someone from my family (not a Singapore resident, this person lives in Europe and holds a UK passport) who will be on holidays in Singapore during that same period would like to join me for my trip to China. We need to apply for it and I wonder if the process is the same for someone living in Singapore and someone that is here on holidays.
Thank you very much for your help.
