do we need every time show the return flight?
I believe some did travel via USA to enter Canada to avoid showing Canada Passport at China Custom

进入美国从来就不需要出示返程机票啊？

how about boarding on flight when you depart China, do they require you to show return flight?

出中国时，中国边检又怎么会检查回中国的机票？难道中国出发到国外的航班，都要求必须要买来回机票？？
