There seems to be many Manchu loan words (vocabulary) in Mandarin Chinese.

I'll list a few here:

lan san 懒散 (lazy)

sui he 随和 (casual)

la ta 邋遢 - originated from Manchu "lete" (sloppy)

mama huhu 马马虎虎 - originated from Manchu "lala huhu" (careless)

guniang 姑娘 (lady)

guye 姑爷 (son in law)

babude 巴不得 (eager to)

dingdang 叮当 (clattering)

luosuo 罗嗦 (verbose)

bieniu 别扭 (quarrel)

zheteng 折腾 (cause suffering)

leizui 累赘 (burden)

qiu 瞅 (look)

I heard there are even more Manchu vocabularies in Beijing and
Tianjin and North-east Mandarin dialects.
