would end in the latter's execution. Some sinologists consider the mortal Oath of the Peach Garden in the Romance of the Three Kingdoms, one of the Four Classic Chinese Novels, to be an example of blood brotherhood, although from a Chinese perspective it is . Undocumented immigrants have also demonstrated fictive kin relationships. Undocumented restaurant workers are known to form pseudo-families in which they cooperate within living and working situations. These relationships benefit the workers by creating a support system that would otherwise be unavailable to those living far from home. These ties are, however, fictive in a strict sense and mean nothing to the people in such pretenses. Some fictive kin relationships have been discovered in Israel in relation to organ transplants. Hospital committees are formed to assess whether the organ donation is from a true family member or from a friend. In order to obtain organ transplants, some individuals are forced to find strangers and pay them compensation for the procedure. However, the relationship between the donor and recipient must be invented as a familial relationship in order to pass through the hospital committee. In this case, fictive kinship is created knowingly to both parties in order to achieve their goals, and is mutualistic in nature. Adoption and foster care have always been grouped into the fictive kinship category (in cases where the child shares no genetic relatedness to the caregivers). The children are normally treated as the adopters' biological kin, receiving a lot of parental investment despite not having family ties. This view has been chastised by some who claim that notions of kinship are not always based on biological determinants. But these links do not mean that the adopters would not love more their biological offspring, given the extra natural motivation of survival. The United States military has also been an avenue to propagate fictive kinship, such as the sense of brotherhood felt by the soldiers. Fictive kinship has been demonstrated among the spouses of military men and women as well. These relationships may facilitate close bonds that are beneficial during times of hardship. Other times, relationships can appear from the outside to be fictive kinship relationships, but the reality is that this appearance is just the result of kinship terminology. Members of the Shanti Nagar village in North India refer to everyone—even strangers—in familial terms. A man would address another man of a similar in
