Abstract: A mahjong game set has a table and four mahjong tile sets. A tabletop of the table has a concaved surface and multiple tile holders; wherein each tile holder has multiple tile standing recesses and multiple tile displaying recesses. Each mahjong tile set has multiple mahjong tiles respectively having different pattern surfaces or character surfaces, and each mahjong tile is spherical. When playing a mahjong match using the mahjong game set, each player selects a mahjong tile and throws the selected mahjong tile hard into the concaved surface of the table. The spherical mahjong tile rolls in the concaved surface and does not slip out of the tabletop.

Abstract: A vertical garden assembly has a frame, multiple pot mounts and a circulating irrigation device. The frame has multiple lateral rods and multiple longitudinal rods arranged in a crisscross pattern to define multiple hanging segments on the lateral rods. Each lateral rod is inclined to a horizontal line to define a high end and a low end. The pot mounts are mounted on the hanging segments. The circulating irrigation device is connected to the pot mounts and has a duct assembly, a reservoir and a pump. The duct assembly has multiple lateral ducts and longitudinal ducts communicating with each other. The lateral ducts are connected to the hollow pot mounts. The reservoir is mounted at a position below the low ends of the lateral rods and is connected with the duct assembly. The pump is mounted between and connected with the duct assembly and the reservoir.
