The ancient Yeming Bridge welcomed two new stone lions, thus completing the set of 'guardian auspicious beasts.' However, the new stone lions are naughty and troublemaking. They always disregard the bridge-guarding rules, causing many jokes. One night, a mother and daughter from a distant place came to look for refuge. The little girl named Shanhu accidentally discovered the secret of the stone lions at night... Night after night, year after year, they depend on each other and keep their promise to protect the bridge, becoming the closest companions in the world. However, the smoke of war disrupted the peace of the village, and also tempered the characters of the two young stone lions. After experiencing separation and rising up, humans and stone lions finally feel the responsibility and bravely take over the mission of their respective inheritance! This is a story full of love, warmth, and growth. Perhaps one day, when the bell rings, we will see the stone lions smiling at us again...
