Qi (器) is a real object or a specific official, position, etc. A qi is something visible, or something one may describe in concrete terms. Every kind of qi has a specific form, function, or capability. Therefore there are clear distinctions between one qi and another. However, a common dao exists in different kinds of qi. The existence of a qi is based on dao. In terms of human affairs, an individual assumes a particular responsibility suited to his position； but he should go beyond his specific capabilities and strive to adhere to and obtain dao.
