"Meet here in sixteen years." The little dragon girl jumped off the heartbroken cliff with these eight words, which also made the relationship between Yang Guo and the little dragon girl more precious. In Jin Yong's The Condor Heroes, their unswerving love still touched many people. But for this "16-year Covenant", Mr. Jin Yong has never given a clear explanation. Why not five, ten or twenty years, but sixteen years?

What did Yang Guo do in the sixteen years after the little dragon girl left? He travels in rivers and lakes, punishing evil and promoting good. He fell head over heels in love and became a chivalrous man, no less than Guo Jing. However, in Jin Yong's works, "heroes" must be regarded as "serving the country and the people" (for details, please refer to Guo Jing and Huang Rong who protect Xiangyang). Just wandering around the rivers and lakes is not enough to support the chivalrous name of "Condor Heroes". So, Yang Guo waited for 16 years and killed Mongolian Khan Mungo outside Xiangyang City, becoming a real "condor hero".

More importantly, Guo Xiang has grown up in these sixteen years. Guo Xiang is also an important foreshadowing in the trilogy "Eternal Dragon Slayer". There are even more rumors that Jin Yong set Yang Long as 16 years respectively, and originally wanted Guo Xiang to be the heroine of the giant condor, just to wait until Guo Xiang grew up to 16 years old before opening a new plot line. This statement is also impossible to verify.
