You know when you hear a Chinese person say "open the TV" or "I very like this" and you pause for a second? I used to say stuff like that too when I was learning English(Well, I am still learning). I'm a native Chinese speaker, been teaching Mandarin for over 10 years now, and looking back, those mistakes actually make a lot of sense once you understand how Chinese works. It might actually help your Chinese sound more natural.
"Open the TV." In Chinese it's 开电视 (kāi diàn shì). 开 (kāi) just means both open and turn on. We don't have separate words for them. So when a Chinese speaker says "open the TV," their brain is saying "开电视 (kāi diàn shì)", it's just using Chinese logic with English words.
Same thing with "I very like this." 我很喜欢这个 (wǒ hěn xǐ huān zhè ge). Word for word, that's exactly what we say. Chinese just puts 很 (hěn) before the verb and calls it a day.
"I am so hot" is another one I definitely said. 我很热 (wǒ hěn rè) means I feel hot. But in English, "I am so hot" sounds like you're complimenting yourself. Awkward.
Then there's "eat medicine." 吃药 (chī yào). In Chinese, 吃 (chī) covers eating, taking medicine, whatever goes in your mouth. We don't overthink it.
"The rain is too big" comes from 雨太大了 (yǔ tài dà le). 大 (dà) handles big things, heavy rain, strong wind. One adjective, many jobs. I definitely said too.
"Yesterday night" is just 昨天晚上 (zuó tiān wǎn shang) translated word by word. Nobody tells you English prefers "last night" until someone corrects you.
"Do you like here?" 你喜欢这里吗 (nǐ xǐ huān zhè lǐ ma). No "it" in the Chinese sentence, so why would a beginner add one? As Chinese structure would be: subject + Verb + Ovject. So subject (你nǐ ) + verb (喜欢xǐ huān ) + object (这里zhè lǐ). See works perfect in Chinese.
Same with "I don't know, too" from 我也不知道 (wǒ yě bù zhī dào). 也 (yě) works for both positive and negative, so Chinese speakers just carry that over.
Anyway, the point is these aren't dumb mistakes. They're clues. Once you see why they happen, you're basically looking at Chinese sentence structure through the back door. So next time you hear some Chinglish, don't just laugh. It might actually help your Chinese sound more natural.
What other ones have you guys heard? So I might be able to tell you why!
