In the west, people respect private property, including intellectual property rights. According to the law, an individual's private property is sacred and inviolable, and his children enjoy the right of inheritance and are protected by the state. Zamenhoff not only spent his whole life writing Esperanto, but also spent almost all his money on the publication of the first book of Esperanto, and lived a poor life all his life. However,1on July 26th, 887, when the first book of Esperanto was published, he solemnly declared: "International languages, like every national language, are the wealth of society, and the author will give up all personal rights to them forever." Zamenhof left the fate of this language entirely to the people who use it, and the people decided its future.

Zamenhoff not only gave up the patent right as the founder of Esperanto, but also gave up the royalties of all his Esperanto works and translations. Any publishing house and individual can use and reprint his works for free. Before his death, he repeatedly refused the remuneration paid to him by publishers and individuals. 1On June 20th, 905, he wrote in a letter to Ashett Publishing House, "There are often various people who suggest me to claim royalties (such as Steed, Martin, Fried, Albert, etc.). Suggested to me two years ago; Later, when beaufort wanted to publish the book Esperanto Library, he also made this suggestion. Loudil also put forward such suggestions for the publication of books such as The Grand Dictionary. However, although I have been in financial difficulties; Although they don't ask me to do any work, make any public statements or take responsibility, they just pay me to thank me; Although I have every right to accept these rewards, I always refuse. "

191212 On February 27th, zamenhof wrote in a letter to esperanto association, England: "Miss Fraier chose some sentences from my exercise book in order to write her textbook, and she wanted to pay me some money for the manuscript. I absolutely disagree. The Council of your association decided to give me the manuscript fee. I am sincerely grateful for this, but this money is absolutely unacceptable to me. " Zamenhoff has always been indifferent to fame and fortune, strict with his children, and will never ask for privileges from society. 1909 At the 5th International Esperanto Congress held in Barcelona, Dr. Henry Dole said that Dr. Zamenhof's genius invention actually brought peace to mankind, so he suggested that the Congress should work hard for Zamenhof to win the Nobel Peace Prize. Zamenhoff thanked Dr. Dole for his suggestion, but he asked the General Assembly not to make such a suggestion and not to put the matter on the agenda of the General Assembly. (See International LanguagesNo. 1909,No. 189, p. 427).

Zamenhof wrote in a letter to General Sebert on July 3 19 1 1, "Of course, I can't accept my travel expenses. So far, I can only accept the traditional treatment of the conference: in the city where the conference is held, my wife and I are free guests, but my children are definitely not guests. Documents issued to them and accommodation provided. In Zamenhoff's letters, it is also found that he has repeatedly declined the funding of friends and esperanto users, and his spirit is admirable. 1905 On May 20th, Zamenhoff wrote in a letter to General Sebert, "I received your letter and 376 rubles with great gratitude. This is a travel expense donated by a complete friend to let me attend the meeting. Although I am very grateful for the kindness of this unknown donor, it is a great pity that I can't accept the money. Therefore, I ask you to convey my sincere and heartfelt thanks to the donor and return the money to him. I will never hide the fact from you that it is actually very difficult for me to attend this meeting. We don't have any savings. My family and I make a living from our daily labor income. Therefore, the travel expenses and three weeks' lost time are heavy enough for me. However, in my heart, my feeling is even heavier: I took other people's money to attend the first major festival of Esperanto. Therefore, I can't accept this generous donation in any case, although I am particularly grateful to you, a respected gentleman and the noble and unknown donor for your kindness. "

1905 July 18, Zamenhoff wrote in a letter to "Very Respected Sir": "Please accept my heartfelt and sincere thanks for your suggestion to pay my travel expenses, but please forgive me, I can't accept your suggestion. I highly praise your good wishes, but I think it would be very bad to travel without your own money. " Zamenhof has been practicing medicine in Lithuania and Warsaw for many years. Although his family is not rich, he still treats many poor people free of charge and subsidizes those in need.

Zamenhof was treated in the Lithuanian city of Veyseye. Here, he is not only superb in medical skills, but also respected and admired. Once on his way home, he saw a woman holding a child. The child is very ill, coughing and wheezing. It turned out that a local quack treated the disease indiscriminately and poisoned the child. After three hours of rescue in Zamenhof, the child was out of danger. Zamenhof not only didn't take anything, but also gave the poor mother a ruble to buy medicine when he left.

Another time, a farmer's house in Weseyer caught fire and his children were burned, so Zamenhof was invited to treat him. He didn't charge for medical treatment, and gave all his money to the farmer, so that he had to borrow money from others to go home.

1887 In the spring, Zamenhoff left kaunas for a trip by carriage, and the driver's horse fell to death due to weakness on the way. Zamenhoff immediately gave the coachman 50 rubles to buy a new horse, and the coachman was deeply moved. Because for him, the horse is the only support of his life.
