Very cost-effective. I've tasted their Premium No.3 and Boutique No.2, and they taste very, very good. Moreover, I have compared many super West Lake Longjing with the same price, and the super Wengguangxi brand also has a third-party certification mark, which is rarely done by manufacturers. And it tastes pure. Among the last batch of high-quality brands of all brands, Weng Guangxi and Lu taste the best. However, the price gap is still relatively large, and the price per catty of Weng Guangxi brand is close to that of 200 yuan. So this Weng Guangxi card is a very good choice.
