Location and Operation hours of Han Zheng Street (Han Zheng Jie) in Wuhan

The Hanzhengjie is a street in that city, where you can find different kinds of shops along that street. It is so long, so I do not think it is very easy to describe the exact location.
In general, the local Qiaokou Road Station of local subway line 1 is close to that place.
For the operation time, it is not certain. Some shops will close around 7 to 8 o'clock, but some will open till ten or even eleven o'clock.

Does this mean if I am from Optic Valley which uses the 2nd line metro subway, I should stop at the 1st line subway interchange that is Xunlimen and go to Qiaokou road? From there on, do I have to take any bus or just in walking distance to hanzheng street? TQ

Yes, you are right about that. After you get off the subway train at Qiaokoulu Station, you should take the Exit A. Then walk southwards along the Qiaokou Road for 650 yards, you will reach the street.
