2. Ancient poems about quality

If she just turned her head and smiled, there were a hundred spells, and the powder and paint of six palaces disappeared without a trace.

Two bends seem to frown, and a pair of eyes seem to be happy.

The face is like a mid-autumn moon, the color is like spring flowers, the sideburns are cut with knives, the eyebrows are like ink paintings, the face is like peach petals, and the eyes are like eyes.

A pair of red phoenix triangular eyes, two curved willow leaves hanging from the brow, pink face with spring force, red lips smiling at the smell.

Cut shoulders and slim waist, slender figure, oval face, delicate eyebrows and eyes, looking forward to flying, the essence of literary talent, forget the customs when you see it.

I don't know how to study hard early, but I regret learning late.

Teenagers work hard all their lives, so don't be lazy about time.

The ancients learned nothing, and it takes time to grow old.

Reading breaks thousands of volumes, and writing is like a god.

Ask where the canal is so clear, because there is running water at the source.

If young people don't work hard, old people will be sad.

If you don't come back in the prime of life, it will be difficult to get up in the morning. Timely encouragement, time waits for no one.

Don't listen to things outside the window, just read sage books.

The edge of the sword comes from sharpening, and the fragrance of plum blossoms comes from bitter cold.

Learn not to explore its flowers, but to dig its roots.

Ten years of hard work, grinding out a sword, the blade of the cold light flashing, but did not try its edge.

Therefore, you can never get tired of reading books, and you are self-aware when you read them carefully.

The river runs to the sea, and when will it return to the west? If a person doesn't work hard when he is young, he will regret when he is old ―― laziness when he is young will make him regret when he is old; Reckless youth makes regretful old age; Idle youth, poor old age

Wise people cherish the short days, but sad people know the long nights.

Don't be idle, it's white and sad.

Thank you.

6. Moral cultivation poems

It's not that chrysanthemums are favored among flowers, but that this flower is even more flowerless.

(Tang? Yuan Zhen's "chrysanthemum" does not mean that chrysanthemums are particularly favored among flowers, but that there are no more flowers to appreciate after chrysanthemums bloom. The sentence implied praise for Chrysanthemum's unyielding character, and Ao Shuang then failed.

2. Be loyal to your art, you don't know your age, and let wealth and fame drift like a cloud. (Tang? Painter, painter, painter, painter, painter, painter, painter, painter.

These two words mean that I have been immersed in painting all my life without feeling old, and wealth is as indifferent to me as floating clouds in the sky. This poem praises the noble sentiment of Cao Ba, a famous painter, who devoted himself to art and did not covet fame and fortune.

3, wealth is not prostitution and poverty, and men are heroic here. (Song? Hao Cheng) Don't be fooled by wealth, be content with poverty. Only when a person can reach this level can he be called a hero.

(Historical Records) Path (xρ): Path. Although peach and plum trees can't talk, their fragrant flowers and sweet fruits attract people to appreciate picking one after another, so that they naturally tread a path under the trees.

The meaning of this sentence is that a person with high moral character will naturally win people's admiration. 5, not indifferent, unclear, not quiet, not far away.

(Three Kingdoms? Shu? Without indifferent cultivation, you can't make your ambition innocent; Without a calm heart and the exclusion of external interference, we can't achieve our lofty goals. Zhuge Liang believes that to cultivate one's morality and study, one must first get rid of the shackles of fame and fortune and avoid impetuousness in order to become a talent.

If you study alone and have no friends, you will be ignorant. (The Book of Rites? If a person studies without friends to learn from each other, he will be ignorant and have little knowledge.

7. Don't forget the past and be a teacher of the future. ("Warring States Policy? Zhao Ceyi) refers to remembering past experiences and lessons for future reference.

8, but there is no stone in the advection, and it is always said that there is sinking. (Tang dynasty? Du Xunhe's Jingxi warns people not to be complacent and negligent, but to be cautious when things are smooth.

Sinking: refers to the sinking of a ship and drowning of people. 9, don't do it with evil small, don't do it with good small.

(Three Kingdoms) Do not do bad things even if they are small, but do good things even if they are small. 10, change it if it is available, and encourage it if it is not.

1 1. Worry and fatigue can rejuvenate the country, and leisure can die. (Song? Ouyang Xiu's History of the Five Dynasties? Preface to "Official History") Hard struggle, hard struggle, is enough to achieve great things; If you covet comfort and indulge in pleasure, you will be doomed to death.

Just: achievement. The original metaphor is to recruit talents to achieve great things.

It can also be used to refer to being knowledgeable and knowledgeable, so as to have deeper attainments. 14, Mei Xu Xun's snow is three points white, but the snow has lost a piece of Mei Xiang.

(Song? Lu Meipo "Notice") Plum blossoms are not as white as snowflakes, and snowflakes are not as fragrant as plum blossoms. Now it can be used to describe that people have their own strengths and weaknesses, and they should learn from each other and learn from each other's strengths.

15, national life and death, every cloud has a silver lining. (Qing? Lin Zexu's "Going to the Garrison to Show His Family") Match: Peace, send.

If it is good for my country, I can give my life. Can you escape because of misfortune and fight for happiness? The poem shows Lin Zexu's noble feelings of putting national interests first and not caring about personal gains and losses.

16, no shoes, Li Wei crown. Don't bend over to lift shoes in Gua Tian (lest others mistake it for picking melons).

Don't raise your hand under the plum tree (lest others mistake it for stealing plums). Metaphor is to be cautious where it is easy to be suspected, pay attention to behave yourself and regulate your behavior.

17, decent people are decent, and villains are always in the same boat. (The Analects of Confucius) A gentleman refers to a moral person.

A villain is a person with bad moral character. These two words are about an upright man is open and poised, who is broad-minded, but the villain is often embarrassed and sad.

18, the mountain is starting, and the scenery is stopping. (The Book of Songs? Xiaoya) Jingxing (háng): Road.

Stop: auxiliary words are meaningless. The original intention of the two sentences is: look up when you meet a mountain, and pass smoothly when you meet a road.

Later, the "mountain" metaphor is noble, and the "scenery" metaphor is aboveboard. A person with lofty moral character like a mountain will be admired by others; People who behave aboveboard will be imitated by others.

19, the lotus has no shelter from the rain, and the chrysanthemum still has Ao Shuang branches. (Su Shi's "Gift") Qing (qíng): Hold up, lift up.

Rain cover refers to lotus leaf, because it is like an open umbrella. When the lotus leaves wither, the lotus leaves as tall as umbrellas will wither. But the chrysanthemum withered, but it still left branches standing proudly in the severe frost.

The poem is lined with chrysanthemums, expressing admiration for the noble sentiments of friends. 20. It is better to die holding incense in the branches than to be blown down in the north wind.

(Song? Zheng Sixiao's painting "Chrysanthemum") would rather die on the branches than be blown down by the cold north wind. The poet chanted with chrysanthemums to express his patriotic feelings of adhering to moral integrity and unswerving determination.
