Hi I have two labels are so close to each other. Only one label is showing, until I zoom in very large scale, but that is not what I want. I want them show next to each other. How can I set the position correctly?
Have you looked into using Feature Weights under Label Class/Position?

You can also examine the option for "Unplaced labels - Never remove" or implement "key numbering" as well.
