A character that probes the unfamiliar and questions
the unknown
探：搭建未知与已知的桥梁
When famous Three Kingdoms-era general Lü Meng （吕蒙） was just 15， he ran away from home and secretly joined the Wu states military campaign against mountain bandits. Returning home afterwards， Lü pointed out to his furious mother that his life-threatening adventure had granted him fame and fortune， asking “不探虎穴，安得虎子？” （“How can one catch tiger cubs without venturing into the tigers lair？”）—that is to say， “nothing ventured， nothing gained.”
From a personal adventure to a national expedition to outer space or the deep sea， 探 （t3n） is the word for the exploration of any unfamiliar or little-known field. In picto-phonetics， the left “hand” radical represents its meaning， and the right， originally gave the character its pronunciation， although this changed over time.
According to the Han dynasty dictionary Explaining and Analyzing Characters （《說文解字》）， 探 refers to extending ones hand to reach for something. For example， “探囊取物” （t3nn1ng q^w&） means to take something from ones pocket. The expression later became a proverb to indicate an easy task， since it takes no effort to reach into ones own pocket.
Other things are better hidden， and may take more time and energy to find. For example， 探矿 （t3nku3ng） means to prospect for minerals; 探案 （t3n3n）， to investigate and find out the truth in a criminal case; 探秘 （t3nm#）， to probe into secrets or explore unexplained phenomena; and 探险 （t3nxi2n）， to venture into the unknown. In particular， the last two are commonly undertaken in remote and inaccessible locations， as in 深山探秘 （sh8nsh`n t3nm#， exploring remote mountains）， or 南极探险 （N1nj！ t3nxi2n， exploring the South Pole）.
探 can also be paired with other verbs to describe different types of exploration. For example， 探索 （t3nsu6） means to explore and seek， and is often used in scientific contexts， as in 人类不断地探索自然界的奥秘。 （R9nl-i b%du3n de t3nsu6 z#r1nji- de 3om#. “Humans are continually exploring the secrets of nature.”） 探究 （t3nji$） means to probe deeply and reflect. For example： 这本书探究的是人生的意义。 （Zh- b0n sh$ t3nji$ de sh# r9nsh8ng de y#y#. “This book probes the meaning of life.”） However， its usually important to look at multiple perspectives and solutions in an exploration; therefore， 探讨 （t3nt2o） means to examine and discuss a topic. For example：
最近经济学家在对经济体制改革做进一步的探讨。（Zu#j#n j～ngj#xu9ji` z3i du# j～ngj# t@zh# g2ig9 zu7 j#n y！ b& de t3nt2o. “Recently， economists are further examining the question of structural reform.”）
Apart from reaching with ones hand， 探 also implies putting the rest of ones body forward. The common usages include 探頭 （t3nt5u， pop ones head in）， as well as 探头探脑 （t3nt5u t3nn2o， pop ones head in and look about furtively）; the latter is often used pejoratively to mean “snooping.” For example： 小偷儿进了大楼后探头探脑地四处张望。 （Xi2ot4ur j#n le d3l5u h7u t3nt5u t3nn2o de s#ch& zh`ngw3ng. “The thief looked around furtively after breaking into the building.”）
In this sense， some 探 expressions can be extended to mean visit， call on， or see. 探望 （t3nw3ng） is to visit someone from afar. For example： 路过北京，顺道探望一下老朋友。 （L&guo B0ij～ng， sh&nd3o t3nw3ng y！ xi3 l2op9ngy6u. “While traveling through Beijing， I dropped by to visit an old friend.”） Similarly， 探病 （t3nb#ng） means to visit patients at the hospital or in their homes; 探亲 （t3nq～n） is to visit ones parents or relatives; and 探监 （t3nji`n） is to visit inmates in prison.
Not all explorations are carried out in the open： 探听 （t3nt～ng， inquire about） usually means to find out information covertly， as in 已经有好几个人来探听新所长任命的消息了。 （Y@j～ng y6u h2o j@g- r9n l1i t3nt～ng x～n su6zh2ng r-nm#ng de xi`oxi le. “Several people have nosed around for news about the appointment of a new director.”） The verb 刺探 （c#t3n， spy on） particularly refers to scoping out a rival， or opposition research. For example， 敌军在刺探我方军事设施。 （D！j$n z3i c#t3n w6f`ng j$nsh# sh-sh～. “The enemy is spying on our military installation.”） The character can also be used in nouns referring to the person sent out to collect the information， such as 侦探 （zh8nt3n， detective）， 探子 （t3nzi， scout）， or 密探 （m#t3n， spy）.
Throughout history， human beings have continually explored the outer limits and unknown spheres of nature and society， from the medical tests of Shennong （神农， a legendary prehistoric ruler of China， sometimes known as the father of Chinese medicine and agriculture）， to the modern search for the “wild man” of Shennongjia Forest. As long as human beings have curiosity， ambition， and a need to survive in the universe， the urge for exploration will doubtlessly persist.
