Wung Ling was a young Chinese medical student who appeared in two Biggles stories. The first story in chronological sequence (though not in publication order) was The Case of the Mandarin's Treasure Chest, part of the Biggles of the Special Air Police anthology. Here, Wung Ling had been a medical student at Oxford for three years. Prior to his departure from China, he and his father had placed their collection f Chinese cultural treasures, mainly ancient art asnd scrolls of literature in a chest and had buried it in their garden in their ancestral home at Pao-tan in Kweichow province in Southwest China. Shortly thereafter the area had fallen to the communist regime and Wung Ling had to flee the country. His house was destroyed and his father, who had remained behind, died. Wung Ling offered the collection to the British Museum if it would recover it. The British authorities agreed to this. Biggles was despatched with his air police crew to accompany Wung Ling to recover the chest. The British Museum reimbursed Wung Ling for his contribution and thie funds allowed him to complete his medical education.b
Biggles met Wung Ling for the second time in Biggles Follows On, a book that was actually published a year before the previous story! Here, Biggles needed to mount an expedition to rescue Guardsman Ian Ross, a British agent, from a prison camp at Kratsen in Machuria in northeastern China. Biggles needed someone to reconnoitre the camp before mounting a raid to effect the rescue and for this he approached Wung Ling. As the text records, Wung Ling had "at once dropped what he was doing in order to take advantage of an opportunity of striking back at a regime that had destroyed not only his own ancestral home, but the ancient culture of his native land."
Wung Ling was parachuted into Kratsen and retrieved three days later. He had performed his mission admirably. By joining with the various Chinese labour gangs, he had not only penetrated the prison camp and gained a thorough knowledge of the layout, but had even managed to speak to Ross, whispering a few words of encouragement and telling him that friends were near. His intelligence proved invaluable in planning the subsequent raid led by Biggles and Gimlet. Wung Ling accompanied this later mission and served as the liaison between Biggles' team which aimed to free the prisoners and Gimlet's team whose job was to blow up the facilities at the base. Again, dressed in his Chinese clothes, Wung Ling was able to move about discreetly. At one point he managed to listen in on a discussion at the house of Commandant Kubenoff and warn Biggles that von Stalhein had arrived.
