Lin Wanqiu originally wanted to marry into the prince's palace and enjoy a peaceful life, but unexpectedly she took over the care of Fu Tian, the legitimate son of Prince Fu Jingyun. She abandoned rigid teaching methods and used the concept of "studying things to gain knowledge" to educate her children along the lines of nature. She took her children to play with mud, make paper kites, and learn about vegetation, and she actually transformed her naughty son into a sensible and intelligent child. She used her unique parenting method to resolve crises such as the destruction of famous paintings given by the emperor. She was recognized by the emperor and was ordered to teach the prince. She also unexpectedly improved her relationship with the cold-faced prince.
