Spanish is more complicated that English at a grammar level and vocabulary diversity, for native speakers and many students it take many years to learn how to be proper using it. As for Google, it does a great work translating English to Spanish but it really mess with the sentence's information and message the other way around. You're English is really good, I only notice that you're not that familiar with it when you use preposition and conjunctions for linking clauses in the sentences. If I might be so bold to rate your proficiency it would be over 9 of 10 🙂

I have tried to find a local Chinese friend but most of them are from the southern region of China and came to my country many years ago, so they don't speak Mandarin.

Thank you for your kind suggestions, I'm taking full note of each one of the remarks you wrote. As a mater of fact, if you see that I write anything wrong or in an unusual way you could correct me as many times as you want. I don't take offense because of this, on the contrary I feel grateful because you're so kind to take some minutes of your time to send me a feedback 😊
