The Chinese characters are likely just an encoding issue. This could be verified by translating the Chinese characters in the email, which seems an obvious first step. Which they didn't take.
Missing the question why Chinese characters were there in the first place.
I just explained, it's an encoding issue. Computers speak in binary, just zeroes and ones. Depending on the encoding, those zeroes and ones can be displayed entirely differently. There are character sets for most languages that use different characters. Arabic, Baltic, Celtic, Cyryllic, Chinese, Korean, etc.
The actual data sent could have been sent as "Lorem Ipsum Dolor Sit Amet" but displayed as "带悲伤的胡萝卜".
When was the last time you got an email from a friend that was accidentally printed in Chinese?
Buy many bridges?
