Jehan was renowned for his nuanced and delicate portrayals of carp, often inspired by the fish he bred at his family home. In this refined composition, the graceful movements of the carp are rendered within a tranquil lotus pond. Celebrated for their strength and ability to swim upstream, carps are commonly seen as emblems of perseverance, vitality, and abundance. Within Asian culture, they are also closely associated with good fortune and prosperity. Jehan experimented with watercolour collage on crinkled rice paper in the late 1980s and later perfected this as his distinctive technique. He was given his first two solos by Frank Sullivan at Samat Art Gallery in 1968 and 1970. In 1961, he won a Merit Award in the Art India exhibition and in 1969, he won the 1st Prize (Category D) in the prestigious Salon Malaysia for his work entitled Sad October. He studied at the Nanyang Academy of Fine Arts in Singapore where he was mentored by Cheong Soo Pieng. After graduating in 1960, he taught at Pay Fong Middle School in Malacca for 22 years. He turned fulltime into art in 1983.
