世界爱牙日：各地换牙习俗各不同

　　Spain

　　在西班牙，会是一只老鼠把枕头下面的牙换成一枚硬币。

　　Slovenia

　　In Slovenia, a mouse replaces the baby tooth under the pillow with a candy during the night。

　　在斯洛文尼亚，一只老鼠把枕头下面的牙换成糖果。

　　Japan

　　If it is a lower baby tooth, throw it up onto the roof; and if it is an upper tooth, throw it underneath the 'en-no-shita' (the lower portion below the floor of a Japanese house). It is done so that the upper tooth grows healthy downwards, while the lower tooth upwards。

　　在日本，如果掉的是下牙，就扔到房顶上去;如果是上牙，就放在外廊地板下面。这样是为了让上牙向下长，下牙向上长。

　　Vietnam

　　Both the upper and lower teeth are thrown up over the house。

　　在越南，不管上牙还是下牙都会扔到房顶上去。

　　Korea

　　The same method as that of Japan。
