江东 / Jiangdong (Warring States)

江东 / Jiangdong enters the wiki through 《资治通鉴·秦纪》102-2｜孔子在鲁国的身世之谜 as the region 黄歇 / 春申君 requests after arguing that his Huai north fief borders 齐国 and should be converted into commandery-county administration by 楚国.

The source identifies Jiangdong with former 吴国 territory and treats it as safer than the exposed northern border. Its advantages are geographic: the Yangtze River provides a barrier, the region lies far from 秦国, and it gives Chunshenjun a more secure personal base while Chu’s main strategic danger remains in the west.

That makes Jiangdong part of the wiki’s fief-security branch. The move is not identical to 封地筑城安全幻觉 because Chunshenjun is not merely building walls around an exposed fief; he is trading an exposed frontier position for a deeper and safer regional base. The episode still treats the move skeptically because it may reveal personal safety preferences and a distorted threat map.
