Hello, science is promoted farming solve for you.
"50 do not build house. 60 do not plant tree. 70 do not make the clothing. 80 do not visit friend. " this is the adage that archaic shedding hands down, say ancient adage is the crystallization of forefathers wisdom, for instance " long October, short May, not long not 28 months short " , "If grass does not sprout involuntarily, if the person is inadvertently underdeveloped " , "Pig of the arch that feed a swine is not had in groove, divide the spoils not all dogfight " etc is the adage that the ancients passes summary of social experience place to come out, circulate up to now.
The ancients life is extremely low, a little ancient adage is already malapropos. "50 do not build house, 60 do not plant tree " , these two words are to show the person is in after entering old age, not was necessary to make long-term plan, do not use up him place remnant to do a few pairs without much time the thing that oneself do not have much great sense. 
50 do not build house, after means passed 50 years old, do not build a house, because lid house is an important matter the life with extinct gold, wait for you to had built the house, you have not likely the lot goes be being enjoyed well; And 60 do not plant tree, also be same meaning, passed sexagenarian later, be not planted arboreous, because tree becomes a useful person time is very long, inherent " 10 years of tree, person of hundred years tree " view, so sexagenarian plant again later tree, likely you cannot see tree blossoms soon in person the picture that enters extremely big tree.
Common saying of not all of course ancient time is put in contemporary still can applicable, archaic fertility is low, the life is tough, wait without effective remedy to the disease, the life of the ancients is not very long commonly, the mean life of feudal society period has 37 years old only, and say after average person is 40 years old old, for example Su Shi is in " Jiangchen child go hunting of secret administrative division " in write " an old fellow like me sends a boy a little mad " . And contemporary the promotion as standard of living, of medical treatment technology develop, national mean life achieved 76 years old 2015. So 50 years old still are worth prime of life, still struggle in working station go all out in work, the country also increases ceaselessly according to the life of people, put forward defer to retire, let an old person give off light as before on working station calorific.
Qing Dynasty is in toward Ceng Tingmei " Tan of ancient adage idle. Kind tree adage " in proverbial to this explain the point of view that appealed to him " ancient adage tells: 50 do not build house, 60 do not plant tree, 70 do not make the clothing. Zhang Shen's fair father Yu 70 years old of advanced age. The old person ate very sweet mandarin orange on banquet, cultivate the nucleus of mandarin orange come down to hope to in the future can often mandarin orange samples. But the guests that be present are laughed at in the dark, the time that does not think is impossible to eat mandarin orange, think Yu Nian issue is afraid high already have not enough time to eat. Yu ate mandarin orange to eat ability 10 years to die later " people thinks the age is old, with respect to should easy and comfortable life, this kind of judgement that sets out to go out from experience only is wrong, derisive other became him absurdity instead.
The person is living be about to seek taller life state, cannot constrained the limitation at the age, accomplish not disappoint life times, create value, enjoy the life. (2)
