Fengxian, the county name of the Tang Dynasty. In the second year of the Western Wei Dynasty (AD 553), pucheng county was located in Puchi. In the fourth year of Kaiyuan in the Tang Dynasty (AD 7 16), Fengxian County was established, and now it is located in Pucheng, Shaanxi Province. In the fourth year of Song Huangkai (AD 9 17), pucheng county changed its name. Pucheng county, Shaanxi Province.

The netizens upstairs misread the Baidu entry "Fengxian" (/view/965624.htm): in the fourth year of Tang Kaiyuan (AD 7 16), it was changed to "pucheng county place" and could not be read as "pucheng county place". For example, "changing old clothes" can't be pronounced as "changing old clothes". However, the expression of this entry is not complete enough and it is easy to be misunderstood.
