Compass === 
 On what grounds was the compass reference by Li Shu-hua removed? The newer research does not contradict Li Shu-hua's observation. In fact, it stresses his point, since the wording demonstartes that the passage does NOT contain a reference to a magnet. 
 *"However, it should be pointed out that in the Louen-heng text, on which Tchang Yin-lin and Wang Tchen-touo based their hypothesis, there is no explicit mention of a magnet.Li Shu-hua: “Origine de la Boussole 11. Aimant et Boussole,” Isis, Vol. 45, No. 2(1954), pp. 175-196 (180)"    
 *Original text (180): "On peut remarquer que dans le texte du Louen-heng il n'y a pas de mention explicite d'aimant. Pour arriver au résultat ci-dessus indiqué, on est oblige de poser quelques hypotheses."    
 ::Twas not I who removed this. Anpersonalaccount maybe? In any case, I remember restoring a citation from him in the picture caption to the right.  

 Hey Gun Powder Ma, how could a word like magnet appeared over in the ancient texts by the way? The word magnet, which according to this article came from Greek word "magnesian stone".    
 ::Perhaps he means the Chinese word (i.e., 攝石) for magnet? In any case, we should not expect Wang Chong to have truly understood what magnetism was; he simply described the effects of the geomancy ladle and bowl.  
 Well, we shall look out sources on this.    

 Hey, I just added and replaced the old source with a better ones! Lol
