The poet Song Zhiwen of the early Tang Dynasty actually killed his nephew in order to seize his poems.

The familiar saying that flowers are similar every year but people are different every year is still recited by us. Among the 42,863 poems in the Tang Dynasty, only this line appears in two poems at the same time, namely "The Sad White-headed Man" by Liu Xiyi and "Thinking" by Song Zhiwen. The authors of these two poems also have an unusual relationship. They are actually nephew and uncle. What's even more strange is that the competition for the copyright of this poem even led to a brutal murder.

During the period of Empress Wu Zetian, Song Zhiwen won the first place in the Royal Poetry Competition twice. . However, as Song Zhiwen's talents gradually faded, no new works became popular for a long time, and his power and position were not as good as before. When Wu Zetian once again recruited famous people from all over the world to join the palace to advise on political affairs, Song Zhiwen was not on the list. Extremely annoyed, he wrote a poem to express his love for Empress Wu, but Wu Zetian used his bad breath as an excuse to keep him thousands of miles away. Song Zhiwen realized that his talents as a scholar were exhausted and his official career would inevitably end. How eager he was to create an amazing new poem again to prove his ability as a royal champion poet.

Liu Xiyi, he accidentally saw the poem written by his nephew Liu Xiyi. Flowers are similar every year, but people are different every year. He couldn't put it down and was amazed. Thinking that his nephew's poems were unknown, Song Zhiwen was tempted to steal poems. He believed that such a good line would definitely help him return to the top of the poetry world and regain the appreciation of Empress Wu. Unexpectedly, Liu Xiyi rarely had such a satisfactory work, and he was reluctant to hand it over to his uncle. Song Zhiwen became angry and deceived his nephew into a trap that had been set for him. He filled his mouth and nose with yellow sand and pressed his chest with a sack until he suffocated to death.

Song Ziwen's desire for power has long been transformed into a coveting of good poems, and now his coveting of good poems has turned into a sinful motive for murder. The good verses he occasionally picked up from his master finally evolved into The culprit of a murder.
