As a father cannot, except in exceptional circumstances, deprive his son of the family inheritance, it follows that a man's power of making a will is severely limited. The division of property between brothers may take place either after their father's death or while he is still living. The process is called _fên chia_,--Division of the Family. When brothers _fên-chia_ it means in general terms that each takes his share of the family inheritance and leaves the paternal roof: and the document which is drawn up to define and give effect to the agreement is known as a _fên-shu_ or written statement of the details of division.[90] The share of each participating member of the family is clearly stated in the _fên-shu_, and each is given a copy of the document to hold henceforth as his title-deed. A _fên-shu_ is in Weihaiwei generally drawn up by mutual agreement between brothers after their father's death. If the arrangement is made during the father's (or mother's) lifetime, a portion of the property usually remains in the parent's hands as _yang-lao-ti_--"Nourish-old-age land." After his or her death the _yang-lao-ti_ is made to bear the cost of the funeral, and what remains is divided up among the heirs. A portion of the property is sometimes set aside as _chi t'ien_ (sacrificial land) to be cultivated in turn by all the brothers participating in the division. Sometimes the father keeps no _yang-lao-ti_ for himself but merely stipulates either that he shall be supported by all his sons in turn or shall receive from them a fixed proportion of the produce of their several shares. The former of these arrangements works very well when the members of the family are in complete harmony with one another; but sometimes a discordant note is struck either by an unfilial son or (much more often) by one of the sons' wives, who perhaps fails to treat her husband's father with proper respect.[91] A woman in China, be it remembered, practically severs her connection with her own family when she marries; her husband's parents are henceforth regarded as her own, and she owes them just the same obedience and filial respect that are owed them by her husband. The _patria potestas_, in fact, is exerted not only over sons and grandsons but also over their wives. But in practice we find that sons' wives do not always, to put it mildly, show the meek and reverential obedience to their _kung-tieh_, or father-in-law, that Chinese law enjoins and public opinion considers desirable.
