two people drink tea, since the need for someone to pour tea, because the emperor is the Lord, and can not lift a teapot to pour tea to the mansion.
the magistrate was scared, but he was not good enough to kneel on the ground to thank Lord long. So the brainwave, bending the index finger, middle finger and ring finger, tapping three times on the table, the right to take the three big knees.
this custom is so popular, but today this custom is not the meaning of any three knelt kneeling, but a way of expressing gratitude.
generally speaking, when we first pour tea, we should first respect the old and then the humble, and accept the response when pouring tea.
