On May 6, writer Li Yaling (), who co-wrote 2 Yu Zheng dramas "Pretty Maid" (2010) and "Spell of the Fragrance" (2010), offered to be a witness to support Chiung Yao's lawsuit. She claimed that back in 2008 Yu had asked her to "borrow" "Plum Blossom Scar"'s story for a new script, but she refused. Li Yaling further claimed that Yu had copied scenes from the Singaporean drama "The Little Nyonya" (2009) for "Pretty Maid", an action that also damaged her reputation because she was listed as the writer. She also claimed that Yu Zheng once told her that as long as plagiarism does not exceed 20% then the courts would have no case. Another writer Zou Yue () also claimed to have heard the "20% rule" from Yu Zheng.
