Wannianlaoer system]
Although there are indeed parents (families) who treat everyone equally in this world, there are more parents (families) who are partial or even partial. Under this circumstance, a group was born, and their name was: Lao Er.
Generally speaking, those with the character "" are more likely to be valued and hoped for, while those with the character "young" are more likely to be favored and cherished. The "second child" neither occupies the elder nor the younger. They are usually mediocre and the easiest to be ignored.
The Wannian Lao Er System was born precisely because of these "Lao Er".
