Use a pot with a bowl or vermicelli or transparent cement. I control the amount of tea, usually two-thirds bags. The first time to make tea is about 10 second. The second soaking takes about 30-40 seconds, depending on the tea. In short, the time is short and there is a green taste, and it has a cooked taste. The third bubble extends about 10 second on this basis, and so on. This is my method of making tea, you can learn from it.
