From the perspective of Iceberg Model, we analyze levels and structures of quality of migrant workers from knowledge, skills, social role, self-cognition, traits and motives. On the basis of these situations, we put forward countermeasures: value rural education and enhance skill training; make clear occupational planning and set up correct sense of value; assist migrant workers in facing the reality and adjusting their state of mind in working; coordinate interest relationship and call upon social care; rebuild mental world and construct harmonious society.
