I don’t believe in AI translation Apps, for now I think. Depending a hundred percent on these apps could lead us to make silly mistakes. I’ve seen a post from an English teacher who was learning Mandarin. The learner showed great interest in Chinese culture and talked about the differences between Chinese culture and her own. She mentioned that taking off shoes while entering a home is a good and healthy custom, blamed her father for often walking around with muddy boots at home in the mean time. Here is what she said, “my father is vile(in Mandarin),” but according to the context, she apparently remarked(she probably wanted to say ...) that her father didn’t care that much and was a bit slovenly. The disapproving term(the negative term) in Mandarin covers both of the meanings above, it’s likely to be tricked by simply glancing at translation Apps or some online dictionaries. Just now, I texted “get a grip on…” on Google Translate, it gave out an output similar to “calm down” in Chinese though. To summarize, for correct understanding of specific content by an unknown(foreign/second) language, I practice what it should be, rather than seeking quick help from AI.
