Slurp your food。

吃东西时砸吧嘴。

In Japan, most commonly when eating noodles and soups, slurping shows your appreciation of the food to the chef. The louder the better! You may also drink directly from the soup bowl -- spoons are uncommon. Furthermore, never cross your chopsticks, lick your chopsticks, or stick your chopsticks vertically into a bowl of rice. It's considered very rude in Japan and many other Asian countries, including China。

在日本，吃面喝汤极其寻常，发出啧啧声是对厨师食物的肯定。越大声越好!你还可以直接端起汤碗来喝汤——调羹反而用的不多。另外，千万别把筷子交叉，舔筷子或是把筷子垂直插在米饭中间。这在日本以及其他亚洲国家包括中国，都是极其粗鲁的表现。

Eat only with your right hand。

只用右手吃饭。

Sorry lefties -- in India, the Middle East, and some parts of Africa, it is considered unclean to eat with your left hand。

左撇子对不住啦——在印度、中东以及非洲某些地区，用左手吃饭是不卫生的表现。

Don't offer to split the bill。

别想着AA制。

In France, splitting the bill is considered the height of unsophistication. Offer to pay the bill in its entirety or someone else will。

在法国，AA制被看成不懂人情世故。要么就请客，不然就等别人买单吧。

Eat with your hands。

用手吃饭。

In Mexico, it is considered an almost snobby practice to use a fork and knife。

在墨西哥，用刀叉吃饭是十分势利的表现。
