Whether men, women, old or young, when it comes to traveling and visiting, they first think of this picturesque place. Tourist groups from all over country should not miss this place when organizing tourism activities. This is Forbidden City in Beijing, most sacred place in hearts of Chinese.

The current Qing court dramas, including "The Legend of Zhen Huang" and other TV dramas, are popular on Internet, which also gives people more opportunities to learn about Forbidden City in Beijing and history of Qing Dynasty. Many people will clean "The Legend of Zhen Huang" four times and five times, and details will be too detailed.

So, friends, did you notice where emperor lived? That's right, this is Hall of Mental Development. The emperor in play works here, receives ministers and lives here at night. Even when he was crazy about his concubine, he was in this place. In end, according to Zhen Huan's plan, emperor lay down on bed in Mental Growth Hall and closed his eyes forever.

Actually, Palace of Mind Realization does exist in Forbidden City in Beijing, and it is not deliberately fabricated by TV dramas. Many friends who visited Palace Museum in Beijing must have visited Hall of Intellectual Development.

However, many friends have reported that The Mental Cultivation Hall makes people feel very cold, no matter if it's winter or summer, and evokes a gloomy feeling. This topic has also attracted some attention on Internet, and many netizens actively participated in discussion. So why is this phenomenon happening?

In recent years, with gradual deepening of research, experts have gradually come up with some ideas to solve problem.

Firstly, Mental Development Hall was built during Ming Dynasty. The original purpose of building was not to be used as an emperor's residence. Most of emperors of Ming Dynasty lived in Qianqing Palace. However, Emperor Jiajing of Ming Dynasty ignored government because he was obsessed with achieving Taoism and becoming immortal.

To follow ideal of immortality. A new palace was rebuilt, called Hall of Mental Development. The purpose of calling it Hall of Mental Development is precisely to pursue a pure heart and few desires.

After death of Emperor Jiajing, his descendants also followed this habit and used Hall of Intellectual Development as emperor's residence for public affairs and recreation. The Hall of Mental Cultivation's status in history also gradually rose, gradually replacing Qianqing Palace and becoming emperor's official residence.

After Qing army entered pass, Ming dynasty completely perished, and Qing dynasty occupied Forbidden City in Beijing. At beginning, emperors still lived in Qianqing Palace, including Kangxi Emperor and others.

But over time, during reign of Emperor Yongzheng, in order to more conveniently conduct state affairs, emperor's residence was moved back to Hall of Intellectual Development.

At this time, Hall of Mind Development also added a new function - administration of state affairs. The Office of Military Aviation was also established here as best place where Emperor met with Minister of Military Aviation to load and issue orders. Many decrees were issued and spread throughout country.

Therefore, Dian of Mental Cultivation has lived with several emperors for over 200 years since her birth. But why is it getting damp and cold in current Hall of Mind Cultivation? Even in midst of scorching sun, being in Hall of Mental Cultivation does not feel like coolness, but piercing coldness.

Many netizens have started discussions on Internet, and some of their speeches are superstitious, thinking that as residence of emperor, many people must die here, which may be source of gloomy here.

But superstition cannot be trusted. At beginning, person in charge explained that reason was that most of buildings in Mental Cultivation Hall were made of wood. In order to prevent wood from rotting and dehydrating, water was replenished from time to time. . Therefore, room will be very humid.

Later in 2015, after full planning and preliminary preparations, construction of Mind Cultivation Hall began. Also, it was this renovation that dispelled many rumors and perfectly explained reason for this phenomenon. When craftsmen opened up floor of Hall of Mind Development in preparation for repairs, they found rows of pipes under floor.

This should make people praise wisdom of ancients. Over 200 years ago, ancient Chinese were able to provide heating by building pipelines. This is similar to our current winter heating. In winter, hot water flows through this underground pipe, which transfers temperature from floor to inside of Mental Cultivation Hall, thus raising temperature of room.

During reign of emperor at that time, it was such a way to keep warm. But since kingship was overthrown, pipes here have been gradually abandoned, and subsequent generations do not know that there are pipes used for heating under floor of Hall of Mental Perfection. Thus, groundwater in pipe was not diverted.

The source of moisture in temple is caused by evaporation of this groundwater. As for cold, during reign of emperor there was a heating system to increase temperature in room, now these pipes are filled with ice water, so naturally it will be very cold.

Often, many phenomena that we think cannot be explained are actually due to fact that we have not found real cause. As long as everything stays for a while, truth behind it naturally slowly comes to surface. Therefore, before you find out truth, do not listen to unknown conclusions and do not scare yourself.
