A corner of longing, a homeland, and the roots that hold it all together. The story begins in an old house in Chaoshan region in South China"s Guangdong Province. There, the elderly Grandma Shurou has spent her life guarding a weathered wooden door and a box of yellowed overseas qiaopi. Her husband, Musheng, worked far away in Siam (Thailand), and through his letters and remittances, Shurou sustained the family at home. But in truth, Musheng had long since passed away in a foreign land. Nanzhi, a Chaoshan woman living in Thailand, deeply grateful for Musheng"s kindness while he was alive, secretly sent remittances in his name for 18 years - a gentle lie to protect Shurou"s unwavering wait. Back in the Chaoshan homeland, Shurou endured hardship and never gave up, embodying the profound meaning of "home" as the very cornerstone of life. The moon-worshiping ceremony, the ritual of Kung Fu tea, the pickled olives - these scenes carved into the bones of the Chaoshan people are the longing for home felt by countless wanderers, and they also form the bedrock of Chinese cultural identity.
