sure, never hurts to make an effort, even just for the humility of it all. i’ve got covered most colors, counting to 10, hello/goodbye a few technical words and some dirty phrases for good measure.
that being said, i used to work with a technician who could pretty much converse in mandarin…and he was actually from India! Very impressive and got a lot of respect from the factories and was able to cut down on a lot of the “OK, no problem sir” BS.
