After her daughter passed away, Wu began looking for the traces her daughter had left. She traced many places in several months and took a lot of photos. Using these photos, she took down the memories of her daughter and published a picture album titled "Love Cannot Wait" with her daughter's tones. The books have not a price and Wu printed them with her own money and mailed them to the parents and children in need.
Thanks to the picture album, Wu gradually stepped on a road of public good.
"It is a commemoration for me. I helped others and others also helped me. They make me realize that many people need me and there is a reason for me to live, though I lost my daughter."
Since then, Wu began to help more children and mothers. She set up a studio to help young girls and many of them going astray regained a new life with her helps.
