Analysis of information sources in references of the Wikipedia article "Wentian module" in English language version.
The two space labs, Wentian, or Quest for Heavens, and Mengtian, or Dreaming of Heavens
This means the two future science modules, Wentian ("Quest for the heavens") and Mengtian ("Dreaming of the heavens"), cannot dock directly to their planned radial port locations. [...] To account for this, each module will carry a Russian Lyappa robotic arm — like the ones used on Mir for the same purpose — to move the module from the forward port to its respective permanent location on a radial port of Tianhe's docking hub.
