Why my texts on ugui disappear when the camera moving far from the gameobjects

There are some gameobjects in the World, and some texts as their labels.

Those text is on ugui, and moved following gameobjects by scripts:

 public void LateUpdate()
  {
      Vector3 pos = followStar.position;  // get the game object position
      Vector3 screenPos = Camera.main.WorldToScreenPoint(pos);
      Vector3 showPos = new Vector3(screenPos.x, screenPos.y+30, screenPos.z);
      transform.position = showPos;
  }

If the main camera is near from all the gameobjects, everything seems normal. However, if it moves far from them, all labels(texts) are invisible! They do be active, and is in the area of canvas, even can be seen in "Scene View", but disappear in "Game View".
