As the family could not get in touch with the Prime Minister, the first letter was written to the Guangzhou secretariat king. Zhang Jiuling was a brilliant poet in the Tang Dynasty, but his talent was always buried because his family had no connection with the prime minister. Later, I came up with a way to write a letter to the then Guangzhou secretariat and show his poems to Wang. When Wang saw Zhang Jiuling's poetic talent, he recommended his poems to Emperor Xuanzong of the Tang Dynasty at that time. Emperor Xuanzong of the Tang Dynasty read Zhang Jiuling's poems, praised them and took part in the imperial examinations. Zhang Jiuling passed the imperial examination and eventually became a scholar, making him famous all over the world.
