We can see each side of a object. Of a thing, we can only see the side of on the table and can't see the side of under the table.
物的兩面，我們都可以看得到，但事的兩面，我們只能看到檯面上的一面，卻看不到檯面下的另一面。
De facto, the thing is true when it is under the table and the thing is fake when it is on the table.
事實上，檯面上的一面都是假的，檯面下的一面卻都是真的。
According to the law, officials and judges must be telling suspecter his/her lawful right when interrogates or trial. The lawful right including 1. Subject, 2.have to remain silent, 3 may appoint counsels, 4.was asked to investigate the evidence favorable. From this we can prove that true is concealed. Besides, for the purpose the hypocrisy is unavoidable
例如行政官員、司法警察、檢察官及法官辦案，依法律規定，應向問案人告知其權利，包括（一）事由（二）得保持緘默（三）得選任辯護人（四）得請求調查有利之證據。由此即可證明，真的一面是被隱藏的。再說，人為了達成自己的目的，虛情假意在所難免。
So that, we can't trust that something had had quoted as an official report or reliable information. For that, we must investigate and analyze it deeply as possible as we can If we want to know the detail about something.
所以說，當官方文件或據可靠消息被引用時，我們都不能據以相信。如欲知曉內情，就必需對該事務作深入的探討及解析。
How to investigate and analyze? The answer is to break two myth of "second reality" and "mouthpiece" of the public communication.
探討及解析的方法無它，只要破解傳播學上的兩大謎思即可。此兩大謎思分別為「第二真實」及「傳聲筒」。
Second reality is that someone who narrates something is according to his/her own conception and do not completes the reality, because everybody have his/her own different conception.
第二真實，就是陳述內容，係傳播者的主觀意思，而非真正的真實，因為每個人的主觀意思都不相同。
Mouthpiece is narrator deliberately voicing for someone, just like a news paper voices for its sponsors, readers and advertisers.
傳聲筒，就是陳述者是有目的地去為某人或某機構發聲，正如報紙是為贊助者、讀者及廣告主發聲。
