Zhang Pengzhou's main argument lies in the determination of the year of Xue Tao's death. At the beginning of Shu in Weigao Town, South Vietnam offered peacocks. According to Xue Tao, he opened a pool and set up a cage to live in. In the autumn of the fifth year of Daiwa, the peacock died. The following summer, Xue Tao also died. Liu Yuxi's poems and Bai Juyi's Liu Yuxi's books all mentioned this matter. Related poems have been quoted in detail by Zhang Pengzhou. For example, what is Liu Yuxi's History of Peaceful Xichuan? ":"Yuer has been buried by the golden ring, and Cui Yuxian withered with the autumn grass. But see the lotus with dew, a few lines of red tears clear the pool. "Hibiscus blooms in summer and withers in autumn. There are three or four sentences in the poem that the lotus is still covered with dew, such as red tears dripping into the pool, indicating that it died in summer. In the second sentence of the poem, the peacock died, "first withered with autumn grass", which refers to the autumn when Tao died last year.
Peng of Sichuan Institute of Literature and History believes that Xue Tao was born in Zhenyuan in 1912 and died in the autumn and winter of Daiwa in six years, at the age of four or seven or eight.
Peng's textual research mainly includes: 1. In Shu Jian Pu, it is said that "Duan Wenchang is the epitaph", and Duan Wenchang saved Shu twice, once in the winter of six years in Daiwa, and died in nine years in Daiwa. Accordingly, Xue Tao's death must be nine years before Daiwa. Second, Xue Tao's poetry collection includes the poem Building a Side Building. The side building was built in the spring and summer of Daiwa and completed in the autumn. Xue Tao's "The Wing Building" has the phrase "Autumn is eight windows above the clouds", when Xue Tao was still there. Thirdly, Xue Tao's poetry collection includes Li Tanghua and Li Taiwei. Li Taiwei, Li Deyu, Daiwa went to Sichuan in October of four years, and Daiwa left in winter of six years. Li Deyu once wrote poems that hurt Xue Tao. Although Shi Li has died today, Liu Yuxi's He Xichuan Li Shangshu What can be used as evidence. According to this, Xue Tao will die before Li Deyu leaves office, that is, before the Yamato winter six years ago. According to the above research, Peng believes that Xue Tao's death was at the time when Li Deyu was about to leave office and Duan Wenchang was about to take office, that is, in the autumn and winter of Yamato six years. There is also a Wanli-washed engraving of Xue Tao's poem: "Tao Yi heard it with poetry, and the guests had a secret talk." When his life is high, he is ordered to pour wine and write poems. According to this, Peng researched: In the first year of Zhenyuan, Wei Gao was appointed as our ambassador in Xichuan, and after twelve years of peace and reconciliation, he was called Wei or Wei Xianggong. The poem "On the Duke of Wei" is found in Xue Tao's poetry collection, so after seventeen years of Zhenyuan, it was necessary to serve wine as a poem. Wei Gao is Xue Tao and He. When he served as the secretariat, he was 15 years old and was summoned for a year or two. Then Xue Tao was seventeen or eighteen at this time. It can be inferred that Xue Tao was born in the first year or the second year of Zhenyuan.
There are different opinions about when Xue Tao was born and when he died. Mr. Zhang Pengzhou can only say that "the only hope is to unearth the original epitaph as soon as possible".
