Taiwan Province singer Kigi Choi's alias is "Little K". How did it come into being? thank you

The origin of "Little K" is that Zi Qi was born in 1986 and was the youngest girl in the family. She was the youngest girl when she first joined SKM Company. However, due to her sweet and lovely appearance, her agent Cooley's mother called her "Xiao Qi" or "KK". Later, because of her habit, both her agent Kooly's mother, assistant Peter and fans like to call her "Little K"! Zi Qi himself likes the name "Little K"!
