White Cloud Temple in Beijing
Feng shui, Chinese medicine, Chinese astrology, Chinese face reading, taichi, qigong and other Inner, Outer, Hard and Soft martial arts forms all have a common root, that is yin-yang, Five Agents and Eight Trigrams theory system, the very foundation of Daoism. 
In the 8th century, the Tian Chang Temple was built in Beijing to house a statue of Lao Tzu. Although it burned down in 1202, the statue was saved . In 1224, Genghis Khan ordered the reconstruction of the temple. It came to be known as the White Cloud Temple. Today it is one of China's oldest and largest Taoist temples, housing the office of Taoist Association of China.
In Chinese, Taoist temples are not actually called temples, but Guan. Guan means something like to look at or observe. This is a reflection of the Taoist belief that understanding the Tao comes from a direct observation of nature, rather than scholastic theological studies.
Here are some images of the Temple taken on a full moon Sunday, which is a popular time for Taoists to visit. It is especially popular with Cantonese, whose dialect and fashion stand out from local Beijing residents.
The White Cloud Temple is in southwestern Beijing, directly behind the Broadcasting Building. It was called the Temple of Heavenly Eternity during the Tang Dynasty and the Temple of the Great Ultimate during the Jin Dynasty. It is the largest Daoist architectural complex in Beijing and was the headquarters for the Dragon Gate sect. Although historical records indicate that there were Daoist temples in Beijing during the Tang Dynasty, it was not until the early Yuan Dynasty that they came to be built on a large scale. The Yuan Emperor Shizu (Kublai Khan), whose reign lasted from 1260 to 1293, appointed a Daoist priest from Shandong province to the position of "National Teacher,"which nominally put him in charge of all Chinese Doaist affairs. This priest‘s name was Qiu Chuji, but he was commonly known as the Sage of Eternal Spring (Changchun Zhenren). While Qiu Chuji was in Beijing, he resided in the Temple of the Great Ultimate, which he expanded and renamed the Temple of Eternal Spring 
(Changchungong). From then on, it became the center of Daoism in northern China. It was not until the Zhengtong era (1436-1449) of the Ming Dynasty that its current name was adopted.
The extant temple was rebuilt in the Qing Dynasty and exemplifies the Daoist architecture of the period. The complex is composed of multiple courtyards set out on a central axis. From front to back the structures are as follows: a memorial archway, the main gate, a pool, a bridge, the Hall of Officials of the Heavenly Censor ate (corresponding to the Buddhist Hall of Heavenly Kings), the Hall of the Jade Emperor and the Hall of Religious Law (corresponding to the rear hall of a Buddhist temple).
In the center of the rear courtyard is the Hall of the Patriarch Qiu, devoted to the worship of Qiu Chuji, and behind this, the Hall of the Four Heavenly Emperors, the second story of which is the Hall of Three Purities (corresponding to the Sutra Repository of Buddhist temples and housing the Daoist Tripitaka). Here one can see the similarity between Daoist and Buddhist temple architectures, though the decorative details and paintings make use of specifically Daoist motifs such as lingzhi fungus, specifically Daoist immortals and cranes, and the Eight Diagrams.
The temple contains a stela with calligraphy by Emperor Qianlong recording in detail the history the history of the temple and the life of Qiu Chuji.
