道教
Taoism is a religion and philosophy originating in China which is based on living in harmony with "the Way" (Tao or Dao). Its main theorician is Lao Zi, which left a strong impression over Kong Fuzi (better known as Confucius) and was later deified. Like him, many Chinese mythical figures have become Taoist saints or gods along with their close relatives. The main deities are Yuhuang Dadi, the Emperor of Jade which rules over destiny, Donghua Dijun, Lord of the Eastern Mountain and of afterlife and Xiwang Mu, Mother-Queen of the West and guardian of the peaches of Immortality, which grant an almost divine status to the virtuous and wise ones.
Taoist principles are naturalness, spontaneity, simplicity, detachment from desires, and most important of all, wu wei (i.e. "Doing nothing" = not occupying oneself with/not interfering in the affairs of others). The principle of balance (represented by the yin yang symbol) is also important.
In-game, Taoism is restricted by a lack of special casus belli. However, the stability offered by the absence of a short reign penalty should not be underestimated. With the +2 bonus for Stewardship, it is easier to have a large demesne and to receive more taxes. If your ruler has the Han culture in addition to the Taoist faith, he gets +2 Imperial grace every month towards the Chinese Emperor (if the Emperor is Han and Taoist, which he is over long periods of time) which can be spent on a multitude of useful features to improve the domain and strengthen the ruler. Getting a peace treaty and thus protection from Imperial invasion and military help through an Imperial marriage or Kow-tow is easy for a Taoist Han ruler.
Overall, Taoism offers stability and the option to build tall, i.e. smaller but powerful realms, at the price of fewer offensive options.
Taoism has a unique name for Piety, Te.

道教概观
在游戏中，道教在地图上几乎不存在。唯一一个道教存在在地图上的剧本是769剧本, 此时汉人都护府仍然统治着酒泉公爵领, 而在867剧本辽帝国已经统治了蒙古王国.
在游戏中，中国是大部分，或者说几乎是所有道教角色的来源。当中国皇帝信仰道教时，通过皇恩互动找到一个道教廷臣并不困难，他们常常因为自己的服务而获得一个伯爵领作为奖励。
另一个道教统治者的来源则是许多来源于中国的雇佣兵。麒麟佣兵团和青龙佣兵团是远东地区最强大的雇佣兵，也能持续不断地生成道教指挥官，即便是当中国皇帝信仰佛教（在女真入侵之后, 或者在1066年）或者长生天（在蒙古入侵之后）。偶尔，他们会试着冲出他们的固有区域，其中的一些廷臣也可能会成为冒险家。
冒险家也是另一个道教角色甚至是道教统治者的重要来源。由于其临近中国，于阗王国和费尔干纳公爵领常常成为他们的主要目标。其中一些冒险家能够成功，并建立起自己的公国。
最后，一些事件也能产生道教角色。比如，中原王朝的某个反对者可能在一个统治者的宫廷中寻求庇护；或者当一个统治者遵循上谕进贡马匹作为朝贡之后，中国可能派遣一位商贸官员到统治者的国土上来。
