My dad wants to drink Lan Guiren tea (also known as ginseng oolong tea) who understands, give me a recommendation to buy which brand is the best ah. I'm not sure if you've ever had a drink before, but I'm sure you've never had a drink before. I am specialized in Hainan Lan Guiren tea. Lan Guiren is a kind of oolong tea, but the taste of different origins is not the same. The price is not equal. There are three price levels: low, medium and high.

First, make sure. What kind of Lan Guiren tea you used to drink.
