How to display data in arcmap 10.5.1 ?

[HaiMai]

I created a new point feature class and filled data information into its data attribution. I can not see its data info displayed in the Arcmap.

Are you able to view the points?

How did you edit the feature class?

How did you create the Point Feature Class?

Do you have an XY table containing the Lon./Lat. values? How To: Import XY data tables to ArcMap and convert the data to a shapefile 

Or are you creating the points manually using the Editor Toolbar. If so, then remember to save the edits as well. First create a point, then fill its attributes. Exercise 1a: Creating new points—Help | ArcGIS for Desktop

If you can't see the points, then perhaps you didn't specify a coordinate system and it doesn't agree with any of the other data in the data frame.

If you are expecting to see the attributes, then you have to open the table of the table for the featureclass.

You can 'symbolize' your data if you wish to display one of the attributes as a theme in the dataframe.
