What does this sentence mean, "A friend in need is a friend indeed"?

In the cold season, all the trees withered. Only pines and cypresses stand proudly in spite of the snow and ice. This proverb compares the difficulties that may be encountered in life to the cold winter, and compares the care and help of relatives and friends in setbacks to the unchanging pines and cypresses. It shows that precious friendship will become more brilliant in severe tests and exercises.

"Pines and cypresses can only be known when you are cold, but true feelings can be seen when you are in trouble" comes from Tang Xianzu, a playwright in the Ming Dynasty.

The full text is as follows:

You will know the pine and cypress when it is cold, and you will see the truth when it is difficult. A man knows his companion in a long journey and an inn.

It turns out that colorful flowers bloom all over the world, and it seems that they have all been ruined. What are the good days? Who is happy?

At dusk, clouds and pavilions are green, wind and rain films, smoke and waves draw boats, and what Jinping people especially see is a great shame.

For you, it's as beautiful as flowers and jade, like water passing by, in a quiet boudoir, answering your questions, looking around and feeling sorry for yourself.

In the cold season, all the trees withered, and only the pine and cypress stood proudly despite the snow and ice. It's a long way to go, Xiu Yuan, and you will know that Ma Zhuang is not strong. Only when you get along with people for a long time can you see people clearly. It used to be full of flowers, but now it is a broken well. The beautiful scenery can only depend on the weather. Who will like it now? Xia Yuncui Xuan and Yanyu Painting Boat specially seen by Jinping people.

Introduction of the Main Characters in The Peony Pavilion Resurrection

Du Liniang 1

Born beautiful, he has a gentle, tenacious and persistent temperament, as well as a sentimental, sentimental and infatuated side. I woke up with a dream tryst with Lingnan scholar Liu Mengmei and missed it.

With the help of Liu Mengmei, Shi, Judge Hu, Fairy Peony, etc. and God, she came back to life and finally got married with Liu Sheng after many hardships. Although she lived in a boudoir and was influenced by feudal ethics, she had a rebellious consciousness against traditional ethics and a rebellious spirit against cruel reality in her bones.

What burns in my heart is a strong desire to break away from the feudal cage, break the shackles of Neo-Confucianism, pursue personality liberation and yearn for beautiful love. She died of love and was born of love. She is not only a tragic figure strangled by feudal times, but also a romantic life shaped by art. ..

2. Liu Mengmei

Formerly known as Chun Qing, male, 20 years old, Lingnan scholar, descendant of Tang Dynasty poet Liu Zongyuan, handsome in appearance, extraordinary in temperament, versatile and ambitious, but unlucky, his parents died young, without friends, and he only relied on Liu Zongyuan's servants Guo Tuoxian and Hou Guotuo to manage the flower beds in the orchard to support him, despite his poor life.

Still aim high and study hard, both of them have the ambition to serve the country, but they have no talent. After suffering, they finally realized their ambition and won the first place in high school. Although he is full of books, his heart is not short of justice and heroism, and he is also full of blood and youthful arrogance. He often speaks out against injustice.

He and Du Liniang are faithful because of their dreams, and their true feelings remain unchanged. They risked their lives to dig graves and save lives for Li Niang's rebirth, and achieved peerless love with bold actions.
