Một trong những sở thích của tôi là nghe nhạc, đặc biệt là các bài hát tiếng anh. Sở thích của tôi bắt đầu có khi tôi là sinh viên năm thứ nhất tại Đại học Bách khoa Đà Nẵng. Tôi dành nhiều thời gian cho nghe nhạc khi đang làm việc nhà như quét nhà, giặt quần áo hay rửa bát…hoặc khi tôi ngủ. Tôi thích Taylor Swift và Rihana…họ là những ca sỹ rất tuyệt vời. Tôi có thể học từ vựng tiếng anh khi nghe nhạc và nó cũng làm tôi cảm thấy thư giãn nữa.
Tôi nghĩ đó là một điều tốt và tôi sẽ không bao giờ từ bỏ nó.
