In Luoyang, there is a female named Mochou who can weave damask at age of 13 and pick mulberry leaves at the south of road at age of 14... Artocarpus lingnanensis is used for the beam of Family Lu's house constructed with lily magnolias. The room is full of the fragrance sent out by tulips and styraxes..."
