Mr. Wong is the father of Chang Wong and Ming Woo, and Mrs. Wong's husband. In the Left Behind: The Kids, he made his first appearance in Book 28. Mr. Wong was responsible for recommending his son to Nicolae Carpathia so that he would work in New Babylon as part of the computer division previously headed by David Hassid. He also pressured his own son into taking the "mark of loyalty" by having him drugged with a sedative before the biochip was inserted and the tattoo applied to his forehead. However, when Leon Fortunato as Most High Reverend Father of Carpathianism forced everyone to take the "mark of loyalty" or be put to death, Mr. and Mrs. Wong both went underground, hiding in China until Mr. Wong was executed for his failure to take the mark.
