Unknown Connection Line is the third part of the trilogy that tells the story of “Yinglin's” journey to and arrival at MONDO. The unknown connection line also refers to the connection between people, between cultures and cultures, and between many relationships. The relationship between "Yinglin" and the social group, as well as between "Yinglin" and herself, is revealed. In MONDO's life, and in the two-way interaction with other members of the society and with the society, "Yinglin" has been working towards the goal of becoming a member of the society. The contradictions and struggles are reflected in the specific, metaphorical images and music. The countdown in the work is like the abstract distance between “Yinglin” and the society. The fact that the countdown does not end completely means that the distance between “Yinglin” and the social group does not disappear completely, and also means that “Yinglin's” own cultural identity is not completely transformed. The unknown connection line in the work, which is the embodiment of the relationship between different objects in the work, is also always in flux.

This work as the last of the trilogy, places the relationship between “Yinglin” and the social group at a distance of 0.000001. This also implies that the state of verbuchstabieren's identity is also always in the process of transformation and change. It does not disappear completely, nor does it stop completely. The dilemma of the identity of the intercultural immigrants is also illustrated sideways.
