"History of the Qinghe People" says that Hao Yu was exiled in Shangyang Fort (Liu Xingye)

[History of the Qing river] Let's talk about Hao Yu's exile in Shangyang Fort

　　Where was Hao Yu's original penal colony?

　　In his poem "Seeking Pleasure in Suffering", he has clearly stated that he "seeks pleasure in good labor and suffering" together with "Shangyang Fort" and "wife and children":

Wolongtan outside Shangyang Fort,

Clear water shoals compete with lotus.

Lotus green flowers bloom in the summer month,

The aroma of the attack is mixed in winter.

Move the wife and children in the courtyard to see,

Planted into the tile pot laughing and noisy.

Seeking self-pleasure in the midst of good labor,

Tu de comforts who has mercy.

　　Is there anything else that cannot indicate that Hao Yu was exiled in Shangyang Fort?

　　In Hao Yu's works, "Huanglong" is mentioned several times, referring to the Huanglong Province, referring to Kaiyuan, rather than his land such as Jilin Nong'an, indicating that Hao Yu is related to Kaiyuan Shangyang Fort.　　

　　(1) Hao Yu's poem "Yinggang Xing" has "leaning over dongshu huanglong":

Leaning over the Yellow Dragon,

Red and green sideburns are full of vicissitudes.

I'm not sleeping for more than 20 years,

The end of the world looks back at the moon like frost.

　　(2) Hao Yu also mentioned again in another poem "Drunken Yinzhou Restaurant":

Has put the Mid-Autumn Festival good month back,

Chongyang did not reach the chrysanthemum blossom.

Don't buy Silver State drunk tonight,

He interjected at Huang Longhe.

　　It is no accident that he is in "Shangyang Fort" and repeatedly mentions the ancient Huanglong Mansion in Kaiyuan, indicating that his penal colony is "Kaiyuan Shangyang Fort".
