The documentary Golden Letters' Journey Home took three years to produce and aired on Southeast TV, Strait TV, and Bilibili, with over 30 million views. It systematically uncovers and presents the precious value and deep meaning of "cross-strait letters," selecting 20 touching letter stories.

For historical scene reenactments, the documentary innovatively combines partial animation with live reenactment, using CHINGMU's motion capture system and virtual camera CMVCS for virtual shooting. To meet the needs for warm, delicate emotional expression, the mocap system captures subtle movements like fingertip and brow gestures, perfectly restoring characters' emotional fluctuations and psychological changes. The innovative combination of animated reenactment with traditional documentary techniques opens new perspectives and strategies for cross-strait documentary creation.
