Polarity is expressed in feng shui as yin and yang theory. Polarity expressed through yin and yang is similar to a magnetic dipole. That is, it is of two parts: one creating an exertion and one receiving the exertion. Yang acting and yin receiving could be considered an early understanding of chirality.[clarification needed] The development of this theory and its corollary, five phase theory (five element theory), have also been linked with astronomical observations of sunspots.
Imperial palaces and cities were planned according to feng shui, which became a principle of classical Chinese architecture. Beijing's Forbidden City is an example. A spectacular complex of palaces, administrative buildings, and temples arranged around a series of courtyards, the Forbidden City was the capital of China during the Ming and Qing dynasties.
Plants respond to music, light and positive energy. When plants are thriving and blooming with beauty, the energy in your home is abundant and flowing. If plants are browning, sagging or dying, the energy is clogged and stagnant. Plants are very telling of the energy of your home, so keeping them in your environment and taking the time to fill your space with positive energy will keep the energy fluid.
In a practical world, televisions and laptops are often a necessary evil in your sacred bedroom space. It's impossible to get away from technology, so a compromise solution is to place your TV in an armoire or another cabinet that can be closed when you're finished watching TV for the night. Close your laptop when not being used and store inside a nightstand or drawer. That way, they are at least out of sight and your space while you rest.
In feng shui, it's said that mirrors in front of the bed invite a third person into the marriage. Mirrors are also thought to reflect energy around a space, which could disrupt your sleep. If you do need to have a mirror, make sure it's facing something that you love looking at. (This may seem like common sense, but it's something a lot of us forget about!)
Most of us have at least one mirror in the bedroom, if not more, but feng shui experts advise against this. “If possible, remove mirrors from the bedroom, as the reflective energy causes excess energy in the room that can be disruptive to sleep,” says Morris. If a mirror in your room is non-negotiable, there are a few possible workarounds, according to Laura Cerrano, a certified feng shui expert and CEO and founder at Feng Shui Manhattan. She suggests covering the mirror at night or placing the mirror so it is not facing the bed.
Partly because of the Cultural Revolution, in today's mainland China less than one-third of the population believe in feng shui, and the proportion of believers among young urban Chinese is said to be much lower Learning feng shui is still somewhat considered taboo in today's China. Nevertheless, it is reported that feng shui has gained adherents among Communist Party officials according to a BBC Chinese news commentary in 2006, and since the beginning of Chinese economic reforms the number of feng shui practitioners is increasing. A number of Chinese academics permitted to research on the subject of feng shui are anthropologists or architects by profession, studying the history of feng shui or historical feng shui theories behind the design of heritage buildings, such as Cao Dafeng, the Vice-President of Fudan University, and Liu Shenghuan of Tongji University.
Beginning with palatial structures at Erlitou, all capital cities of China followed rules of feng shui for their design and layout. During the Zhou era, the Kaogong ji (simplified Chinese: 考工记; traditional Chinese: 考工記; "Manual of Crafts") codified these rules. The carpenter's manual Lu ban jing (simplified Chinese: 鲁班经; traditional Chinese: 魯班經; "Lu ban's manuscript") codified rules for builders. Graves and tombs also followed rules of feng shui, from Puyang to Mawangdui and beyond. From the earliest records, the structures of the graves and dwellings seem to have followed the same rules.
