Introduction to the apse: The roof is a volcanic wall-style hard top, and the main ridge is a clay sculpture of "Double Dragons grabbing treasures". Two swimming dragons have their heads paired, their bodies are flying through clouds and mist, and their mouths are facing the tripod in the middle. It is a three-dimensional sculpture with extremely high craftsmanship. There is a Douba caisson on the ceiling of the inner eaves of the bright room, and the statues of Mazu, the Queen of Heaven, and her attendants are enshrined in the niche of the bright room.
