A green wall comprises multiple horizontal support pieces (10), multiple vertical support pieces (20), and multiple bearing containers (30). The horizontal support piece (10) and the vertical support piece (20) are combined by using a locking assembly (T) to form a vertical support. The vertical support piece (20) comprises multiple openings (21). Each opening (21) has a cutting notch (21a) to form a hook portion (21b). The bearing container (30) has a first horizontal surface (31), a vertical surface (33), a second horizontal surface (35), and an inclined surface (37) continuously connected. The first horizontal surface (31) and the second horizontal surface (35) are opposite in bending directions. The inclined surface (37) inclines upwardly and outwardly. The bearing container (30) has multiple mesh openings (31a) for the hook portions (21b) of the vertical support piece (20) to be inserted in, so that the bearing container (30) can be horizontally hooked on the vertical support piece (20). The second horizontal surface (35) can bear a plant container (40), so as to form a light green wall that can provide a planting function.
