Không được. Nếu mình muốn nói "His chair is old" mình phải nói "Cái ghế của anh ấy cũ".
I would like the speaker to speak slower. I hear a second undefined sound in the word ghế and can hardly hear him pronouncing the word anh. Even after I knew what he said. For the native speaker it may be clear, but I am a beginner.
