How did Hua Wuque learn to bury flowers with empty wood?

I accidentally buried flowers in empty wood in middle school.

According to Iqiyi, in the 40th episode of "Little Fish and Flower Bird", Flower Bird and Little Fish draw lots to decide who will find Yu Yan and die together. When drinking farewell wine, Xiaoyu made sure that he couldn't move with hemp boiling powder and left by himself. Xiaoyuer left Hua Wuque with Liu Ye's dice, hoping that one day he could decipher Liu Ye's dice and learn to bury flowers in the empty wood to avenge everyone. When Hua Wuque was disheartened, Liu Ren's dice were accidentally opened after he threw them away. "Little Fish and Hua Wuque" is a costume martial arts drama directed by Jing Wong and starring Dicky Cheung, Nicholas Tse, Yolanda, Fan Bingbing and Yang Xue. It was officially broadcast in 2005. The play is based on Gu Long's martial arts novel A Double Pride, but the plot and character setting have been greatly changed. Mainly tells the story of twin brothers Xiaoyuer and Hua Wuque in the Jianghu.
