While it seems as though the Chinese have plenty of troops to get the job done, all the Japanese have to do is to keep the Chinese off balance and stay away from close in fighting. The Chinese got their eighteen units off the board, but did not have enough left on board to overrun the Japanese lines. The Japanese have but to dodge the Chinese attacks after that and they win out by default. (Note - This is another one where the advantage is strongly on the Japanese side, if it is played by opponents, the weaker player should be the Japanese player.)
