The method of distinguishing true and false Xueling tea is as follows:

1. Observe the color of the tea leaves. Genuine Xueling tea has different colors, while fakes may be uniform in color, dark and even.

2. Smell the aroma of tea leaves. Genuine Xueling tea has a fresh smell, while fake tea may have a strong smell or other smells such as green fishy smell, burnt smoke smell, etc.

3. Check the composition and texture of the tea. The ingredients of genuine Xueling tea include Ganoderma lucidum, longan meat, raw materials, cassia seeds, etc. The texture is fine and even, without foreign matter or particles. The fake ones may have different ingredients or no Chinese herbal ingredients, and the texture may be different.

4. Pay attention to packaging and trademarks. The packaging of genuine Xueling tea is marked with manufacturer information and the trademark is clearly visible; the packaging and trademark of fake products may be inferior or counterfeit registered trademarks.

The above is the method to distinguish true and false Xueling tea. You can also judge by brewing tea and tasting it, but it requires certain professional knowledge and experience. In order to ensure that you are buying genuine Xueling tea, it is recommended that you choose a regular tea store or the official website of a well-known brand to purchase.
