Bing Sheng (2008), a TV dramatization of the life of legendary strategist and Art of War author Sun Tzu, runs the length of the Wu state's power peak period. It gets a little slow at times - specifically when the human drama bits are going on -- but its production values and inclusion of a range of major historical characters make it a great watch.
As usual, though, some additional characters and subplots get thrown in to put some fat on the historical facts. In the case of Bing Sheng, the machinations of a vengeful scion of the Guo clan, which the Sun clan eliminated in Qi, drive much of the first half of the series, giving a face and a name to the Chu enemy. There is also a slightly awkward fictional spy subplot thrown in towards the end, as well as a few liberties taken with having Sun Tzu also serve under Fuchai. The eventual fate of Sun Tzu in the series, however, was actually written well.
The series does well as far as battle scene production and the armory, which is pivotal for a series about the art of war. Probably not very historically accurate, but each nation has its own well-designed style. The strategies used by Sun Tzu are also depicted well; I doubt that there is enough of an historical record to have these considered as actual historical accounts, but they are clearly Art of War in spirit, and Sun Tzu explains them well too. Acting in the series is generally good too, with Zhu Yawen and Zhao Yi doing a superb job portraying the world-weary Sun Wu and the fiery Wu Zixu. But for a few fast-forward scenes, it's a good series with plenty to delight a Chinese history fan.
