Blender uses a right-angled "Cartesian" coordinate system with the Z axis pointing upwards.

Trục +X

Trái / Phải

Trục +Y

Trước / Sau

Trục +Z

Đỉnh/Đáy -- Top/Bottom

You can select the viewing direction for a 3D Viewport with the View menu entries, Navigation Gizmo, or by pressing the hotkeys.

These operators change the view to be aligned with the specified global axes:

Trên/Đỉnh

NumpadSlash

Trước

NumpadSlash

Phải

NumpadSlash

Holding Ctrl shows the other side of the same axis:

Dưới/Đáy

Tăng -- More Ctrl-Bàn Số + -- More Ctrl-NumpadPlus

Quay Lại/Đằng Sau/Lưng

Tăng -- More Ctrl-Bàn Số + -- More Ctrl-NumpadPlus

Trái

Tăng -- More Ctrl-Bàn Số + -- More Ctrl-NumpadPlus

Holding Shift aligns the view relative to the active selection. So you can for example, view a rotated objects side, or align the view to the active face in mesh Edit Mode.

The view can also be aligned by holding Alt-MMB and moving the mouse towards the view to align to.
