Having received the green light, Yang Yuran sprang into action.
She added the master as a friend and sent the four photos, along with the question, "I want to keep these for another two or three days, how can I minimize their harm?"
The master responded in a very down-to-earth and practical manner: Wrap each of them in a piece of black cloth without any gaps. Then tie them up with red wool used for knitting sweaters and place them in the south-facing side where the sun shines.
The two tools were common household items, and it just so happened that Yang Yuran's room was facing south.
She replied with thanks and hurried downstairs to find Mrs. Yang first. Although Mrs. Yang scolded her with seeming ease, she was also fretting inside; when Yang Yuran found her, she was taking apart a quilt, and doing a more thorough job than Yang Yuran had.
