Mortgages in Weihaiwei, as probably in the rest of China, are much commoner than sales. A farmer will generally sell his land only because he must; he will mortgage it on very slender provocation. As a mortgage does not definitely alienate the land from the family, the customary rules regulating this transaction are much more flexible than those relating to sales. Sometimes a piece of land is merely mortgaged as security for a temporary loan, in which case the mortgagor remains on the land;[87] in other cases it is mortgaged because the owner is going abroad or because the opposition on the part of the family to a definite sale is too strong to be overcome. In such cases the rights of cultivation are transferred to the mortgagee. In the great majority of cases mortgaged lands are subsequently redeemed.[88] Some of the customs regarding redemption are rather curious, and strongly emphasise the theory that redemption is a duty which must be undertaken by another member of the family if the original mortgagor will not or cannot do it himself. For example, A and B are two brothers. They _fên chia_, that is to say they set up separate establishments, each taking his own share of the family property. A remains at home, quietly cultivating his farm, while B decides to emigrate to Manchuria. In order to raise some necessary capital he decides to mortgage his share of the family land; but as neither A nor any other relative can provide the amount of money he requires, he is obliged to mortgage his property to an outsider C--a man of different surname who lives in a neighbouring village. This man C takes possession of the land as mortgagee and cultivates it for some years. B meanwhile is in Manchuria, and no one knows how he is faring, or whether he is alive or dead. A now goes to C and tells him that he wishes to redeem the land mortgaged to B. It is obvious that according to strict legality the land should only be redeemed by the original mortgagor. B's name alone is on the deed: A had nothing whatever to do with the transaction. Yet, by custom, C must resign the land to A; not merely because A produces the mortgage-price, but because he is one of B's family.
