Answer
Nawab Rai was the pseudonym Premchand used for his debut short story, "Duniya Ka Sabse Anmol Ratan." It was published in 1907 when he was just 19 years old. Under this pseudonym, Premchand wrote several satirical pieces criticizing British rule and social injustices. However, he decided to abandon the pseudonym and begin writing under his real name to establish a more personal and direct connection with his readers.
