Look at the bottle cap. The color of Wuliangye bottle cap is bright red. Wuliangye's trademark is also printed on the bottle cap. There is an anti-counterfeiting mark 1 at the joint between the bottle cap and the bottle body, and the inner cover of the bottle cap cannot be restored after being torn. The fake Wuliangye bottle cap is not as delicate as the real Wuliangye bottle cap, and it may feel uneven.
