1947 Chinese KMT 93rd Northeast Division Dong Bei Army Unit Patches

Description

This is a pair of patches that came along with some Japanese WW2 patches. I don't know much about these, although the characters on this (東北) is Chinese, which means north-east direction and is sometimes used as a term for the Northeast part of China.
I know that there was a Kuomintang 93rd Division which fought against the Communists in the Chinese Civil War around 1947, so I believe that these may have belonged to that, although I can't say for sure.
Both patches are in good unused condition and measure 2 1/2 inches long and 1 inch tall.
