I'm 99% sure it's a calligraphy brush holder. That it is from Taiwan and features the Seven Sages of the Bamboo Grove is a big give-away. That image is very typical of Chinese brush holders. Here is an example , although this one is carved bamboo rather than ceramic:

Tiki mugs didn't emerge until the 1960s - and far from China.
