As for curing diseases and saving people, their own side is in an absolute mercy party to the villagers, and the villagers will no longer have the right confidence to exchange goods with each other in the transaction, but will be completely vulnerable in the exchange.

Jiang Yu's disadvantage is not to make himself have a condescending position over the villagers, but to get normal communication and exchange. They are pure outsiders to the village, and although the villagers have some friendship with An Bai, they are still indifferent in the process of communication.

It is clear that they have provided them with food that can solve their urgent needs, but the villagers still hold an indifferent and even hostile attitude, which is the natural emotion of human beings towards outsiders, and it is essentially a kind of self-protection.

Jiang Yuyan understands this emotion, because there is a huge barrier between people - language.

Language is a tool for expression, but it is a tool of last resort because it is extremely inefficient: before human beings express it, they actually have already formed the content to be expressed in their minds, and the transformation of this content into language requires a complex thought process.

In the process, the content is reprocessed, and the final result may even be the exact opposite of what was originally intended to be expressed, and almost all languages have one word to describe the situation: lying.

This is the biggest flaw of language as a tool – the fallacy of expression due to the existence of lying.

It has almost destroyed the foundation of mutual trust and understanding between human beings, and the absolute fallacy of the original expression of the content can only occur in the case of communication over a long distance: because the distance is too far to verify the authenticity, there is a possibility of fallacy in the expression.

However, because of the processing of expression by language, even if two people communicate face-to-face, the content of what is said may be completely different from what they think, so that people cannot gain trust from verbal communication, but can only obtain it from the observation of behavior.

Obviously, such observations must be long-term, supported by a large number of observations, in order to be valid. This is the root cause of xenophobia, and this xenophobia was even more serious in ancient societies.

First, in addition to the observation of behavior, people can also verify the authenticity of communication through various conventions, but the earlier the ancient society, people are limited by technical power, the more limited the means of agreement verification can be provided, and the fewer new appointments to outsiders, the stronger the xenophobia.

This is manifested in the later ancient societies, where human beings could establish a certain degree of trust within a large geographical area by means of marriage, correspondence, and conferences, in order to maintain a huge empire or sphere of influence.

In the early primitive society, primitive people from different regions were so hostile to each other that they could not even regard each other as the same human beings as themselves, and regarded each other as the same food as other animals.

Second, people have a limited range of activities, and they can only observe people who are very close to them for a long time. In modern society, through relatively developed transportation, people can maintain relationships and build trust with people who are thousands of miles away, so there is also the term "global village".

But in ancient societies, transportation capacity was extremely limited, and most people probably never left the confines of their villages and towns in their entire lives, and all their relationships were built within a small area of long-term coexistence, and there was no trust in people outside of this range.

In fact, the direct result of this xenophobia is that in ancient society, it was difficult for the management power from the upper level of a power to penetrate into the various regions of the lower level of the Taoist power, and in simple terms, it was called administrative inefficiency.

In fact, this kind of administrative inefficiency also exists in modern times, but it has been suppressed by the advent of the industrial society and the information society, and by the changes in organization, transportation, and information brought about by powerful technology.

In ancient society, the specific manifestation of administrative efficiency was that the management of a wide range of grassroots areas still depended on the squires or low-level nobles who lived in the grassroots areas and were trusted by the locals, and a large number of resources were actually controlled and managed by them.

This serious xenophobia also made it difficult for the ancient army to communicate normally with the villages and towns, and the two sides were hostile because of their distrust of each other, with the ancient soldiers treating the villagers as outsiders and the villagers treating the ancient soldiers as bandits.

Although Jiang Yugang and his party did not appear as army soldiers, but borrowed the disguise of the merchants, although they did not get hostile, the distance between the two sides was still very far, and if he wanted to penetrate the villagers and gain trust, he needed an opportunity to build trust.

It is this kind of opportunity to cure the sick and save people, whether it is the healer or the healed, if you want to cure the disease, you must tell the truth about the information you have, and this exchange of real information is essentially a promise and verification.

Further, if the healer heals the disease of the healed person, it is through the giving of life that the second covenant and verification is realized, that is, I have no ill will towards you, and you have accepted my kindness.

Trust, and effective communication based on trust, was established in this process of agreement and verification, and the identity of Jiang Yugang and his party also changed from an outsider to a recognized person—although there is still a gap with "one's own people", the spontaneous rejection of outsiders no longer exists.

It can be said that it is equivalent to entering an observation period where it is judged whether it is "one's own person", and as long as the observation time is enough, it will naturally be accepted.

Therefore, this is a rather critical opportunity, Jiang Yugang hurriedly asked the old woman: "What kind of fever is it?" ”

"Vomiting, fever all over the body, accompanied by dizziness," the old woman recalled the condition of the little girl's father: "People can no longer get out of bed, and they have invited the doctor in the village to see them, but they are also helpless." ”

"This fever is like this, and it is generally only supported by itself, and I have never heard of a doctor who can save it." A villager sighed: "Xi'er is really pitiful, there is only one father, and his father is so seriously ill." ”

The little girl looked stubborn as if she hadn't heard the words of the old woman and the villagers, and carefully selected the food and the spices in the small basket behind her.

"Chen Ziyu, can you cure this disease?" Jiang Yu asked, and it was difficult to hide the nervousness in his voice. If Chen Ziyu can cure this disease, their infiltration work in Nansang Village will make great progress, and it will provide a great help to win the trust of the villagers.

"This disease...", Chen Ziyu squinted slightly, as if he was thinking. He has always been steady and silent, pondered for a while, and did not ask the villagers and the old woman anything: "It sounds like a swing, if it is, I can cure it." ”

Chen Ziyu didn't say anything, but Jiang Yuyan could hear the confidence in his words. Playing the pendulum, also known as malaria. In addition to the normal fever, fever is so sick that malaria in this rainforest can indeed be not small.

"This little brother of mine is a master of medicine, can I take him to this little girl's house to see how her father is doing?" Jiang Yufu took the opportunity to ask the old woman.
