For beginners, start with mid-grade "pre-rain" (雨前) Longjing—good quality at reasonable prices. Look for: flat, uniform leaves; jade-green color with slight golden hue; fresh chestnut aroma; sweet, non-bitter taste. Avoid: brown or dull leaves, musty smell, harsh bitterness. Buy from reputable sources; taste before large purchases.
