Woo Hyeong Hwa, said that the art of using chalk to draw, combined with calligraphy, is most often used in restaurants or cafés.
The four Korean women took six months to prepare the exhibition with most of the paintings being created in Vietnam. The students involved are Hwang Sook Ja, Kim Eun Jung and Baek Woon Hye.
Woo Kyeng Hwa said she learned to use chalk, after being impressed by chalk paintings at restaurants. She spent from 3 hours to 3 days for drawing.
She said all of her paintings displayed in the exhibition were connected with her memories of Vietnam.
Her husband, Sun Han Kim, is a resident reporter in Vietnam so Woo travels frequently to Vietnam with him.
It took just two days for the chalk artworks to find buyers.
“The fund raised from these paintings will be sent to the charity fund of Korean in Vietnam to present to disadvantaged children,” she said.
