Axis lines and circles for moving

[RobotpowerE7 0]

Yesterday when my son (he's nine) was creating in Mine-imator, he couldn't animate as usual as the red, yellow and blue lines and circles used for rotation and bend disappear from the animation. When he clicked an arm or leg, they wouldn't reappear. Does anyone know how to fix this? I tried searching for answers but didn't find anything. Can anyone help this already stressed out mom with a solution? Thanks in advance!

At the top of the 3D views, there a bar of buttons you can use to turn certain features on/off for a clearer view, the button on the left-most side will turn the control handles on/off.

Certain handles may be hidden if the tabs on the right (Position, Rotation..) are closed.

There will be some options on the top to show those axis moving lines or not, probably it would have been clicked off, click it again

I ever experience the same things about 4 years ago. And I realize that the causing is the same.
