承载 (chéngzài) means to bear or carry, both physically (a load) and figuratively (culture, responsibility). It differs from 承担 (chéngdān), which focuses on undertaking a specific duty or task, and from 承受 (chéngshòu), which emphasizes enduring or withstanding pressure or pain. 承载 often implies the thing being carried is contained or supported, like a vehicle or a vessel.
