I want to use a feedback node in a loop and initializes it every time the loop execcutes, Ni help file said it had a intialize terminal to implement the funciton <Denotes that the Feedback Node initializes every time the loop executes>, while I can't find this initialize terminal.
Any tip will be appreciated.

You need to set the initializer terminal appropriately:
You may want to select the dot (last one described above) for your purposes.

Please attach your VI so we can see how you have the feedback node showing in your code now.

Please look the png file, I want to move the dot icon inside the loop.

Right click on the feedback node and pick the option "Move Initializer One Loop Out".
Then clean up the wiring so the constant hits the initializer dot rather than a separate tunnel.

Look the png, How can I add a feedback node like the fb in the picture?

First question, what version of LabVIEW is that image from? There have been some improvements and changes in feedback nodes since the days of LV7.1 I'm looking at LV2011 right now, and I don't see how to get the "dot" version to show up at the feedback node, only on a loop boundary. At the feedback node, I only get the asterisk version (init on compile or load) or the "i" version (init on first call).
That said, I'm not sure what you are asking now relates to your original question. Your question was originally about loops. This example you show does not have a loop.

The dot will appear on the edge of the loop, like a shift register and not underneath the feedback node as you have shown.
