nhưng anh vẫn thường xuyên đi máy bay về thăm vợ

LMFAO. These so called reporters from Vietnam seem to be very highly educated!!! that's why when we read Vietnamese news I've always come across sentences like this. It looks to me like these reporters just write whatever heck they think in their small brains and then post it on the internet without going through an edition before publishing it.
The one thing i can guarantee you is that if you read a news in English from over here, you could barely find mistakes in such as grammar, spelling and or broken sentences.
