But to migrants, the problem becomes more visible each day as they gradually settle down in cities with a stable income - schooling can separate parents from their children for years.
Now, with China's further push for urbanization, the timing could not be better to tackle this issue. It is not only humane, but also wise.
Humane because millions of families can be reunited and children can build up healthier personalities. Wise because more farmers will be willing to stay in cities for work.
In recent years, factory owners in coastal regions have been faced with periodic labor shortages as younger generations of farmers have been less tempted to work away from home, particularly those with children.
The rising urge for migrant farmers to immerse themselves into urban life has also made reform plans more urgent for authorities to ensure equal access to public services, as was put forward by a report to the 18th National Congress of the Communist Party of China in November.
However, in spite of all the good will and proper plans, equality in education cannot be expected to be achieved soon, just like in many other aspects of Chinese society.
Aside from the wide urban-rural gap between facilities and teaching staff, education quality varies hugely even within urban communities. It is still uncertain what kind of schools will be open to young newcomers.
At the same time, it is vital for supervisory bodies to oversee the application and approval processes to ensure fair play and prevent this good deed from becoming another hotbed for corruption and social discontent.
