In the teaching room, Ji Fengwen asked, "Who can tell me approximately how long the patient has been blind?"

Immediately, a few people in the demonstration classroom raised their hands, while others seemed to be thinking about something.

"You say it."

Ji Fengwen pointed.

"The blindness shouldn't last long, no more than a month at most."

"May I have your name?"

Ji Fengwen smiled and asked, "Mr. Ji, my name is Yang Haifeng."

"How do you judge that the patient's blindness was not long, no more than a month?" Ji Fengwen asked.

Yang Haifeng hurriedly said, "Generally speaking, everyone needs a period of adjustment to their condition and unfamiliar surroundings. If the blindness lasts a long time, the patient will adapt to some degree. However, when the patient just now walked in, he was clearly fearful and timid, and he walked very carefully..."

"Okay, very good."

Ji Fengwen nodded, motioned for Yang Haifeng to sit down, and then said, "Xiao Yang said it very well. So, in our daily clinical practice, as long as we are careful, we can actually find many problems."

"Sit down!"

Seeing the patient approaching, Yun Heng stood up slightly and helped the patient move the stool.

After the patient sat down, Yun Heng observed him and asked, "Is it because you can't see?"

"Yeah." The patient nodded.

"Can't you see anything at all or is it just blurry?"

"I can't see anything at all."

Yun Heng stretched out his hand and waved it in front of the patient's eyes: "No sense of light at all?"

"Um."

The patient nodded again.

"How long has it been?" Yun Heng asked as he pulled up the patient's arm and placed it on the pulse pillow to feel his pulse.

"A week."

This time it was the patient's husband who answered.

"I went to the hospital for a checkup, and they said there was nothing wrong with my retina. They also did a brain CT scan, and there wasn't anything serious either. They said it could be acute retrobulbar neuritis, central retinopathy, or hysterical blindness."

Yun Heng nodded and concentrated on feeling the pulse.

The conditions mentioned by the patient's husband are not easy to diagnose clinically unless there are some obvious indicators. For example, acute retrobulbar neuritis is easier to diagnose if a clear brain tumor or optic disc congestion and edema is found during examination. If not, it is difficult to judge.

"Who did you quarrel with?"

Yun Heng released the patient's wrist and asked suddenly.

The patient bit her lip and said nothing. Her husband said hurriedly, "It was a misunderstanding with my mother."

"Is that a misunderstanding?"

The patient, who had been quiet all the time, asked back angrily after hearing what her husband said.

"Okay, stop talking."

The patient's mother-in-law, who had been following behind, hadn't said a word the whole time. She quickly pulled her son aside and said to the patient, "I'm sorry. I was wrong."

The patient said nothing and bit his lip again.

"Okay, all of you go out, I have something to understand."

Yun Heng said to the patient's husband and mother-in-law.

The patient's husband looked at his wife, then left the clinic with his mother and closed the door.

"Tell me what happened specifically."

After the patient's husband and mother-in-law left, Yun Heng spoke to the patient gently.

In the demonstration room, Ji Fengwen asked with a smile, "Who can tell me what the patient's blindness is like?"

Someone raised their hand again in the demonstration classroom. Ji Fengwen pointed and Liu Feiyu quickly stood up.

"It is anger that causes the Xiang Fire to move recklessly, which leads to the excess of Qi and blood in the Taiyang and Taiyin meridians. This heat rises upwards, stagnates the eye vessels, and causes blindness."

"Yeah, very good."

Ji Fengwen smiled and nodded, then asked, "What's your name?"

"Replying to Mr. Ji, my name is Liu Feiyu."

"Well, sit down."

Ji Fengwen gestured for Liu Feiyu to sit down and said, "Little Liu is right. Anger causes the Xiang Fire to move recklessly. Xiang Fire and King Fire are opposites. The Dictionary of Traditional Chinese Medicine, written by two renowned experts, Li Jingwei and Deng Tietao, states that 'King Fire and Xiang Fire work together to warm and nourish the internal organs and promote the body's functional activities.'"

"Xianghuo generally refers to the Xianghuo of the liver and kidneys. Anger damages the liver."

Then, Ji Fengwen asked again, "Who can tell me why Yun Heng is asking about the patient right now?"

Some people raised their hands again, and Ji Fengwen pointed to Liu Feiyu again.

Liu Feiyu said, "The patient is angry. Dr. Yun's main purpose in asking this question is actually to give the patient a channel to express his grievances and dissatisfaction."

"Okay, well said."

Ji Fengwen nodded again, asked Liu Feiyu to sit down, and said, "So, in our daily treatment, we must not only consider the clinical symptoms and prescriptions, but also the cause of the patient's condition. The seven emotions and six desires can all cause illness. When encountering emotional illness, we must know how to soothe and regulate the patient's emotions.

The female patient told Yun Heng what had happened, and Yun Heng listened patiently.

The matter was actually not a big deal, just some trivial matters at home. The patient and her husband had just been married for only two months, and she was from another place. She was unfamiliar with the place and had a conflict with her mother-in-law as soon as she moved in, so she felt wronged and angry.

Yun Heng did not judge who was right or wrong, he just listened and said a few words from time to time.

After the patient finished speaking, Yun Heng said, "No matter what happens, don't get too angry. Look, you can't even see now. Isn't it more harmful than beneficial? If this doesn't heal, won't it be a lifelong problem?"

"Doctor Yun, my eyes are not going to be cured, are they?" The patient became anxious after hearing what Yun Heng said.

"I'll give it a try."

As he spoke, Yun Heng signaled He Yongfei to call the patient's husband and mother-in-law in, and asked the nurse to bring the silver needles over.

After the nurse brought the silver needles, Yun Heng picked up a silver needle and inserted it first along the patient's nostrils, which is Nei Yingxiang, then to Zanzhu point, as well as Shenting, Shangxing, Xinmen, Qianding and Baihui points in the middle of the head.

As Yun Heng inserted the needles, a lot of blood flowed out from several acupuncture points of the patient.

After the acupuncture, Yun Heng packed up the silver needles and asked the nurse to take them out while he waited.

After about five or six minutes, the patient suddenly said in surprise: "I...I seem to be able to see."

"real?"

The patient's husband hurried forward and held up three fingers: "What's this?"

"three!"

"What's this?" The patient's husband turned into a finger again.

"one!"

"I saw it. I actually saw it."

The patient's husband burst into tears of joy: "Dr. Yun, thank you, thank you."

In the demonstration classroom, a group of young doctors opened their mouths slightly, their faces filled with shock.

Just now, Liu Feiyu and Ji Fengwen briefly analyzed the patient's condition. Many people knew the cause of the patient's blindness and were also guessing how to treat it.

But no one expected that Yun Heng used acupuncture, and the effect was so obvious and immediate.
