A swinging door hinge assembly comprises a primary hinge and a secondary hinge. By way of an axle rotating on a staircase-shaped axle seat in the primary hinge, the door can be opened in either direction, slowly closed, or opened at a wide angle for a long time. The secondary hinge includes an inner and an outer eccentric axle bushing by which the secondary hinge can automatically adjust its axis to be in alignment with that of the primary hinge, i.e., in a co-axial alignment in case of the door hinge assembly generating any eccentric condition. Otherwise, the door cannot be operated smoothly in case the two hinges are not co-axially aligned. The door hinge assembly may be easily assembled or disassembled, between the left and right side primary hinge pieces, and also between the left and right side secondary hinge pieces.
