The Origin Of The Custom Of Knocking Hands

　　喝茶有一种礼数,就是当别人给你倒茶时,为了表示敬意,用手指轻叩桌面数下.这一习俗的由来,据说是乾隆微服南巡时,到一家茶楼喝茶,当地知府不小心知道了这一情况,拼了老命也得去护驾,否则万一出事,小心吃饭家伙.知府也微服一番,以防天威不测.到了茶楼,也就在皇帝对面末座的位上坐下,皇帝心知肚明,也不去揭穿,久闻大名、相见恨晚的装模作样一番.皇帝是主,免不得提起茶壶给这位知府倒茶,知府惶诚惶恐的,但也不好当即跪在地上来个谢主隆恩,于是灵机一动,弯起食指,中指和无名指,在桌面上轻叩三下,权代行了三跪九叩的大礼.敬茶喝茶是人之常情,又咋知你是微服皇帝,反正你敬我茶,我叩这么几下,也不花多少功夫,省得后患无穷.于是这一习俗就这么流传下来.为了简便,也用食指单指叩几下.

This is a version and a version:

Knock by hand

Friends and relatives are coming to you.

Last year, Songjiang built the city for one thousand and two hundred years, and I had the honor to participate in this celebration.

In the conversation with friends in the literary circles, I heard such a legend, and I learned the meaning of expressing thanks with fingers and tables.

It is said that the emperor Qian Long traveled to the south of the Yangtze River and came to Songjiang. He brought two eunuchs, dressed in plain clothes, and went to a tea shop to visit them.

The tea shop owner took a long mouth tea to hang up the tea, lifted up the teacup, Lala, Da la la, Da la la three spills, the cup was just a shallow cup, and there was no splash out of the cup.

The emperor Qian Long saw in his eyes that he was happy in his heart and asked, "why do you not pour more spilt tea and sprinkle a sprinkling of water instead of sprinkling three more?" the boss replied with a smile: "Sir, this is the rule of our teahouse, which is called Phoenix three nod."

When Emperor Qian Long heard of him, he grabbed the boss's water hoist and picked up a teacup. He also wanted to learn the new trick of "Phoenix three nods".

The cup was poured to the eunuch, and the emperor poured tea to the eunuch. This was not an anti ceremony. In the palace, the eunuch knelt down and shouted three hail, hail, and ten thousand years old.

But in these three teahouses, the teahouses of the miscellaneous teahouses have exposed their identities. This is a matter of life and death.

This action has been handed down so far, expressing gratitude to relatives and friends for tea.
