It was for these reasons that Quang was chosen as the instructor of Yin by Yat Huang, who, without possessing any official degree, was a person to whom marks of obeisance were paid not only within his own town, but for a distance of many li around it.
At length the time arrived when Yin would in the ordinary course of events pass from the instructorship of Quang in order to devote himself to the commerce in which his father was engaged, and from time to time the unavoidable thought arose persistently within his mind that although Yat Huang doubtless knew better than he did what the circumstances of the future required, yet his manner of life for the past years was not such that he could contemplate engaging in the occupation of buying and selling porcelain clay with feelings of an overwhelming interest.

Quang, however, maintained with every manifestation of inspired assurance that Yat Huang was to be commended down to the smallest detail, inasmuch as proficiency in the use of both blunt and sharp-edged weapons, and a faculty for passing undetected through the midst of an encamped body of foemen, fitted a person for the every-day affairs of life above all other accomplishments.
"Without doubt the very accomplished Yat Huan is well advised on this point," continued Quang, "for even this mentally short-sighted person can call up within his understanding numerous specific incidents in the ordinary career of one engaged in the commerce of porcelain clay when such attainments would be of great remunerative benefit.

Does the well-endowed Yin think, for example, that even the most depraved person would endeavour to gain an advantage over him in the matter of buying or selling porcelain clay if he fully understood the fact that the one with whom he was trafficking could unhesitatingly transfix four persons with one arrow at the distance of a hundred paces?
Or to what advantage would it be that a body of unscrupulous outcasts who owned a field of inferior clay should surround it with drawn swords by day and night, endeavouring meanwhile to dispose of it as material of the finest quality, if the one whom they endeavoured to ensnare in this manner possessed the power of being able to pass through their ranks unseen and examine the clay at his leisure ?" "In the cases to which reference has been made, the possession of those qualities would undoubtedly be of considerable use," admitted Yin; yet, in spite of his entire ignorance of commercial matters, this one has a confident feeling that it would be more profitable to avoid such very doubtful forms of barter altogether rather than spend eight years in acquiring the arts by which to defeat them.

"That, however, is a question which concerns this person's virtuous and engaging father more than his unworthy self, and his only regret is that no opportunity has offered by which he might prove that he has applied himself diligently to your instruction and example, O amiable Quang." It had long been a regret to Quang also that no incident of a disturbing nature had arisen whereby Yin could have shown himself proficient in the methods of defence and attack which he had taught him.

This deficiency he had endeavoured to overcome, as far as possible, by constructing life-like models of all the most powerful and ferocious types of warriors and the fiercest and most relentless animals of the forest, so that Yin might become familiar with their appearance and discover in what manner each could be the most expeditiously engaged.
"Nevertheless," remarked Quang, on an occasion when Yin appeared to be covered with honourable pride at having approached an unusually large and repulsive-looking tiger so stealthily that had the animal been really alive it would certainly have failed to perceive him, "such accomplishments are by no means to be regarded as conclusive in themselves.
