Hi Tian,
It’s probably not a Blender Version thing.
What are your Keymap Settings; are you using the Blender Keymap, or the Industry Compatible, (or the Blender 2.79). Are yoiu Selecting with Left or Right MNouse Button?
Do you get nothing at all, when using W (RightClickSelect) or Right Clicking (LeftClickSelect), or something else than you expect?
Any other information that might be helpful?
