A 75-year-old retiree from Brazil has won acclaim on the Internet for an Instagram account he created to stay in touch with grandchildren in the United States and South Korea.
Mr Chan Jae posts watercolour art every day to Drawings For My Grandchildren, which has 56,300 followers.
The captions - which are addressed to Mr Chan's grandsons and feature parallel translations in English, Portuguese and Korean - are written by his wife.
The pictures on the Instagram account capture the Chans' inter-generational, transnational and cross-cultural life.
One recent drawing, showing an adult man kneeling before his father, is captioned: "It's amazing we can watch Korean TV dramas in Brazil. This touching scene is from a hit drama called Gentlemen Tailors."
Another still life, replete with fruit, says: "Brazil is famous for many fruits. You guys must have been so happy to learn you can find guava in Korea, a typical Brazilian fruit."
According to BBC News, Mr Chan's son 45-year-old Ji Lee is a creative director at Instagram's parent company Facebook and helped to set up the wildly popular art account so that Mr Chan could communicate with his two grandchildren in South Korea.
BBC News reported that the Chans moved from Seoul to Sao Paulo in 1981, but their daughter eventually returned to South Korea while their son headed for New York.
