Season 1 of A Clear Sky Beneath One Umbrella tells the story of Hua Xiaoman, a young woman who brings an old umbrella left behind by her grandmother and travels to the Cheng family's umbrella shop, hoping to have it repaired. Determined to preserve the cherished umbrella that holds so many memories, she stays at the shop to become an apprentice. Under the guidance of Cheng Muyan, a reserved and taciturn umbrella craftsman, she learns traditional skills such as splitting bamboo strips, boiling tung oil, and mounting umbrella fabric. As the two spend their days together, they look after a traditional oil-paper umbrella shop and carry on a five-generation-old craft. From splitting bamboo and making umbrellas to taking on apprentices and passing down their skills, they remain true to the spirit of craftsmanship amid the warmth and bustle of the old streets. Along the way, a gentle and enduring affection blossoms between them, as they create a clear sky beneath one umbrella, a world of their own.
