Hello, I know if I scroll through the threads I will probably find it but I'm sure this is a quick answer for many, so appreciated.

First time coming through SIN and am curious if I need to know anything / where to go etc., in reference to my connecting flight. Different terminal? Need to go through security?

Arriving on Air China from PEK then onto Singapore Airlines. We have about an hour and a half I believe. Any feedback is appreciated.
