Aside from the fact that this is a Christian Church, I can't tell much about this postcard and the descriptors on the back are all in Chinese.
Look at these stamps! (Placed in the lower left-hand corner. The address was on the left side too.)
My observation of the many postcards I've received from countries with character-type (as opposed to letter-type) languages is that the handwriting is beautiful, not at all like the scrawl that comes out the the US and Europe. I wonder if languages with characters require a greater attention to detail?
One postcrosser even wrote in her profile a plea to please write neatly.
