Gold is the gold of the five colors, the yellow is gold, the white is silver, the red is copper, the green is lead, and the black is iron.

Xue didn't know anything about the five-color gold, she planned to go to the imperial study on the way back to the East Palace, but she didn't expect that after the practice, she would already be unable to open her legs, so she was lazy at the moment and asked Sima Cheng directly.

Although Sima Cheng didn't know what exactly happened, he remembered that he had encountered the little eunuch door near the school yard in the afternoon, so he roughly guessed three points.

"Back to Your Majesty, the book "Xunzi" once said: 'Jade is in the mountain and the grass and trees are moist', which means that the five-colored gold is on the mountain, and the surrounding plants and trees will be affected by it."

When Xue heard this, Mu Ran nodded, her eyes became a little misty, and she immediately changed her posture, trying to get rid of her sleepiness.

"Then do you know where there is five-color gold in Dayu?"

"The mine follows the mountain, there are various types, and they are scattered all over the world, among which iron is mainly in the east, copper is in Danyang, and gold and tin are mainly in the south of the Yangtze River."

Yizhou has many mountains and rivers, and the local area also has its own copper and iron mines, although the scale is not large, but the weapons used for the palace and the daily utensils of the local people are still more than enough.

Sima Cheng went to the mountains with General Yang when he was a child, General Yang studied weapons, and once, the two saw the veins on the Gobi when they went up the mountain, and General Yang would explain the relevant knowledge to him. If you see the relevant content in an ancient book, you will also pay a little attention.

"...... like this" Snow's eyelids began to grow heavier, and just before she was about to close her eyes, she suddenly woke up with a cleverness.

The flickering deer eyes looked at Sima Cheng blankly, Xue paused, and finally remembered what happened before, she patted her face, trying to sober herself up, and then stood up suddenly, because she forgot about the fact that her legs were still sore, and her butt did leave the chair, but Xue shrank into a ball of pain.

The pain hit the whole body, and the person suddenly woke up a lot, and accidentally found a way to keep himself from falling asleep, Xue slowly straightened up, and decided to stand down like this.

Sima Cheng couldn't help but twitch in his heart when he saw the twisted appearance of the snow, and there was an indescribable feeling.

"Your Majesty has encountered something troublesome today."

Xue was still struggling with the soreness in her legs, and seeing that Sima Cheng still knew something about these things, she just wanted to discuss it with Sima Cheng. So, Xue truthfully told Sima Cheng about Father-in-law Li's visit to the imperial study today, including her worries.

"Your Majesty is reasonable, just as your subordinates just said, the common iron and copper deposits are all over the place, but they are not in the central government, and their actual mining rights are estimated to be mostly in the hands of the feudal kings in various places or the local bureaucrats with greater power."

Listening to Sima Cheng's words, Xue couldn't help but start to make trouble, she tried all kinds of ways before, using a roundabout way, that is, she didn't want to have a direct conflict with the king and the gate valve, but there are only so many mineral deposits at the moment, and there seems to be no other way than forcible seizure.

"Hey......" Xue sighed, "So I can only rob them?" But I can't grab it. "A dignified generation of kings has been reduced to worrying about a small mineral deposit.

Sima Cheng also fell silent, since ancient times, iron and salt have been an important source of government in all dynasties, and private trading has been allowed in history, and as a result, the merchants who deal in salt and iron are richer than princes, such a good business, those kings and gate valves will not let go easily.

"It would be nice if there were new deposits...... That way, I don't have to rob anyone else. ”

Xue's muttering accidentally got into Sima Cheng's ears, he was slightly stunned, and then as if he remembered something, the corners of his mouth couldn't help but rise, and his handsome face lacked a trace of coldness and a trace of evil spirit.

Sima Cheng arched his hand and said to Xue:

"Report to Your Majesty, my subordinates have an idea, although it can't solve the urgent need, but it may be worth a try."

"What?" Xue showed a look of surprise on her face, and walked towards Sima Cheng in a panic, as a result,

In areas where salt and iron are produced, salt officials and iron officials are set up to manage them. The salt monopoly is produced by the salt people under the supervision of the government, purchased by the government at a fixed price, and transported and sold by the government. The iron monopoly adopts the government to oversee all aspects of iron ore mining, iron and steel smelting, iron casting and sales.

In the Eastern Han Dynasty, the monopoly of salt and iron was abolished and a tax system was implemented. The Three Kingdoms and the Two Jin Dynasty paid attention to exclusive purchases, and the taxation system was revived during the Northern and Southern Dynasties. From the Sui to the early Tang Dynasty, the special tax on salt was abolished, and the market tax was the same as that of other commodities.

After the Tang Anshi Rebellion, financial difficulties and the salt monopoly began to be implemented again. Since then, successive dynasties have strengthened the monopoly of salt, and implemented a tax system on iron, which is no longer regarded as the same as salt.

A wise man does not boast, and a man who boasts has no wisdom; Blocking the holes of communication knowledge, closing the doors and windows for transmitting knowledge; Frustrate your own edge and free yourself from your own troubles; Conceal your own brilliance, mingle yourself with the world; This is called profound and subtle Xuantong.

Therefore it is impossible to be close to him or to be distant from him; It is impossible to profit him or to victimize him; It is impossible to make him noble or humble, so he is valued by the people of the world.

It is an attitude towards the world, a method of joining the WTO, not a compliment. It is the soul of "with its light and with its dust"; There must be a measure of forgiveness for others, a measure of forbearance for slander, a measure of vain acceptance of advice, and a measure of tolerance for things.

Frustrate its sharpness and resolve its disputes: It means to resolve the chaos in a weak and unprofitable way. It refers to the peaceful method of dealing with the world without showing its edge, and the original intention is the embodiment of the Taoist idea of ruling by doing nothing.

Since January, His Majesty has made some achievements in the scriptures and classics, but the way of governing the country and the courtesy of a gentleman still need to be used in the world.
