In the special episode of the program "Who Wants to Be a Millionaire", singer Ho Trung Dung had to stop at a difficult question related to famous painter To Ngoc Van. Despite the help of advisory group member Ha Viet Hoang, both still could not find the correct answer.
Question number 12 has the content: "The name of famous painter To Ngoc Van is given to a location located in which celestial body in the Solar System? " with four options: A - Jupiter, B - Mercury, C - Mars, D - Venus.
