Hot

1. Put one tea bag into the tea pot and pour hot water
2. Rotate the pouring of hot tea until it is distributed evenly across all tea cups

Cold

1. Add one tea bag and 500-1000ml of water. The essence of the tea bag will be extracted when enough water has been added.
2. Put your container inside the fridge and wait for 1-2 hours for it to cool. During this period, use a chopstick or other tools to stir the tea and adjust it to your taste preference. Also remove the tea bag when you are satisfied with the taste.

Hope this helps

"How to make delicious cold brew green tea."

"Step 1: put one tea bag into a water container, and fill it with 500ml to 1l of water.
If you want quicker extraction of the tea, pour water directly onto tea bag."

"Step 2: Put in refrigerator for 1 to 2 hours, and intermittently stir until desired flavor is achieved at which point you may take out the tea bag. If you intend on keeping the tea refrigerated for a longer period of time, please do not forget to take the tea bag out."
