dlaczego zapytałem? ano dlatego, znaczek po prawej na twoim klocku wg mnie powinien być odwócony, czyli oryginał nie lustrzany tylko obrót o 180st
Posting the "福" character is a tradition for Chinese people during 春节 [chūn-jié] Spring Festival each year.
The "福" character is often posted upside-down. It is said that this is because the character for "upside-down", "倒" [dào], is a homonym of the character for "to arrive", "到" [dào]. So this means that "福" (happiness, good fortune, etc.) is "arriving". (source)
