In a viral video shared by poet Kumar Vishwas, a Bihar teacher is seen singing "aeiou" to teach students difference between vowels and consonants. "I wish we were taught... by such a musical teacher, then even we would have spoken English with the same fluency as Shashi Tharoor," Dr Vishwas tweeted. Later, Amitabh Bachchan retweeted the post with clapping emojis.
