datlechinvn We do not have non-English language packs installed at this community, so unfortunately you cannot change the language here. Ultimately, most of our content here is going to be in English, so I apologize if that makes it inaccessible. I regret that, as 010101 discovered, Google Translate doesn't work well on our site, I hope Google can improve its functions on forums like this to provide a better experience. You could manually copy/paste words you don't understand into Google Translate or another online translator to get a translation if you needed.
In short, I'm afraid we don't have a good solution for this right now.
