Place 4-5 grams of tea leaves into the Zhi Sha tea pot or Gai Wan, pour in boiling water and cover it for 3-5 seconds, Pour out the tea water into the tea cup(s) and drain away. The first steeping is not intended for drinking and is used for the purpose of washing the tea leaves and warms the tea cup. It’s also a means of decaffeinating. Caffeine is highly water soluble, so it is one of the first constituents of the leaf to be extracted in the steeping process. Usually most of the tea's caffeine content is released in the first steeping.You can enjoy any tea virtually caffeine-free (with little sacrifice of flavor) by discarding the water in the first steeping and adding fresh hot water to the now largely decaffeinated leaf. Every steeping increase 3-4 seconds,  minimum can steep for 5-7 times or more.
