1, Ning Chuan is older than Biaman. Ning Chuan was founded in 1706, which is a classic British black tea brand, while Yaman was founded in 1989, which is a young brand.

2. Ning Chuan's Biaman tastes richer. Ning Chuan's tea series includes classic black tea, fruity black tea, green tea, herbal tea and other flavors, while Yaman is dominated by black tea. So Ning Chuan is good.
