Just kidding, who makes us covet the rewards from the system? … Where is this? Siheyuan? The layout is smaller! ! ! Han Ling, who owns the chemical industry system, always touches the heartstrings of a lot of big guys every time he makes a move. Jeans, yoga pants, Dacron, nylon, spandex, acrylic...
