Cui Shen in Chinese / Japanese...

神龍 or Shen Long literally means “god dragon” or “divine dragon.”

神龍 is a spiritual dragon from Chinese mythology that controls wind, storms, clouds, and rain. Historically, farmers in China avoid offending this dragon, as it could result in a drought or flooding of their fields.

Shen Long has blue/azure scales and appears on the beautiful robes of some Chinese emperors.

Sometimes romanized as Shen Lung and sometimes written as 神竜 in Japan with the pronunciation of Shinryū or Shenron. It can also be a given name in Japan.

This is a Chinese surname that romanizes as Shen from Mandarin or Shum from Cantonese.

In Japanese, it can be the surnames Chin, Chimu, Sen, Sun, Shin, or Shimu.

The meaning is to sink or heavy.

This 沈 character is a variant of 沉.

精, 氣, 神 are the characters jing, qi, and shen.

As a set, these three characters are known in English as the treasures of traditional Chinese medicine, the treasures of Qi Gong, or the three treasures of Taoism / Daoism.

Sometimes this set is titled 三寶 (sānbǎo) or “three treasures,” but here, we're writing each treasure out.

Here's how these characters are perceived in this context...
Jing: nutritive essence; refined; perfected; pure
Qi: vitality; energy; force; breath; vigor
Shen: spirit; soul; mind; being

To keep it simple, you can use “essence, vitality, and spirit” to define these.

參宿四 is the title for Betelgeuse (star in the constellation Orion) in Chinese.

Also known as “α Orionis” (Alpha Orionis), Alpha Ori, or in Japan the Heike-boshi or Heike-star.

Note: 参宿 (Shēn Xiù) is the name given by ancient Chinese astronomers for a constellation of three stars (the three naked-eye visible belt stars of Orion). Therefore, 參宿四 means the Fourth Star of the constellation of Three Stars (which sounds like a joke). As telescopes got better, it should be noted that there are actually 10 stars in the constellation.

神舟 is the name of the Chinese spacecraft “Shenzhou.” The name means “divine craft” or “saintly vessel.”

The name is a play on words in Chinese, as there is an alternate name for China that is pronounced “Shenzhou” but means “Divine land” or “Land of the Gods” (just the second character is different).

The first flight of a Shenzhou spacecraft was in 1999, with more missions following. The next is planned for 2008, and will include China's first “spacewalk.” The tenth Shenzhou mission is planned for 2015, when China has promised its people that a Chinese astronaut will walk on the moon (or at least orbit the moon - there are two ways to interpret the announcement made in 2005).

For those of you concerned, this word is pronounced more like “Shen Joe” (with a slightly soft “J”) than the Romanization would suggest.

2016 Update: I wrote the above in 2006. Imagine that, 10 years later, none of the promises came true.
