Hi, Kris, the stamps might the same ones, but there are many different products around them. And this time I mainly want to introduce the attitudes and concepts of the author. By the way, your Belarus field mouse is quite cute. I think it's just between a real mouse and a cartoon mouse. :-) And the one with mouse and ox is pretty unique, generally the mouse is more often depicted with last year's pig.
Hi, Vayolene, your Wallis & Futuna rat is drawing a Chinese character Shu, Perhaps he is studying Chinese or practicing his Chinese signature. :-) And pineapples are regarded as a lucky fruit because it's a pun in the local accent of Fujian Provice in southern China, and a must-have fruit during the Spring Festival there.
Another commonly used pun of Shu.
Mouse and Belong have the same pronunciation in Chinese. so in the year of the rat, people often change Belong to Mouse for fun and luck.

In this postmark of Zhengzhou City, there is an idiom of 4 characters. The last character should be Belong, but has been changed to a mouse. The idiom means: it belongs to nobody else but me! Now with a mouse in it, it is funny and joyous, just good for the new rat year.
