Dear everyone, especial English native speakers

I'm conducting a graduation research on mistranslation of public signs in Vietnam (Vietnamese - English bilingual signs). Data collection is now done and I have to analyze every single sign to find the translation errors and count and classify them. However, to make it more precise and reliable, I desperately need some help from English native speakers :'(. Of course if you want to learn or are currently learning Vietnamese, I'm very pleased to be your language partner. Thank youuu!!!
