Tang Yuren, a "stone gambling family" in Tengchong, beat Feng Zhongcai, another jade family, in the game; on the way to Burma to find jade, the two fought wits and courage. Feng Zhongcai's daughter Feng Juan fell in love with Tang Yuren; the appearance of Sun Dongyan, a famous jade appraiser, made Feng Zhongcai seem to have a chance of winning. Soon, the Japanese army was about to occupy Tengchong. Tang Yuren generously funded the Chinese Expeditionary Force to go to Burma to fight against the Japanese army. However, Tengchong was finally occupied by the Japanese army with an empty city. The Japanese army began to plunder jade frantically in Tengchong, and used various cruel means to force Tang Yuren to hand over the jade king carving "Greater East Asia Co-Prosperity Map" to dedicate to the Japanese emperor. Tang Yuren dealt with the enemy with superhuman wisdom and courage.
