Ohh, you mean Qin Shihuang. Sorry, my Japanese is indeed too rusty.
Actually, feudalism had seen a brief resurgence after the end of Qin with the establishment of Han dynasty. But after a
failed rebellion against increasing centralization, emperors had always tried to find excuses to reduce powers of feudal lords. The ways they achieved this was quite interesting as well. For example, the imperial examiners were compelled to check closely whether the gold the lords handed over for rituals were pure enough. If not, it served as a dishonorable act towards the throne and their titles were revoked. The Edict of Tuien (Extending Favours) enabled gavelkind succession for feudal lords (before that only primogeniture was permitted), which eventually broke the feudal lands down into powerless tiny tidbits. The Law of Zuoguan (Adjunct Officials) prohibited appointment of councilors who served only the lords but not the throne (i.e. banning inviting courtiers). These acts together basically destroyed any remnants of Chinese feudalism. And centralized bureaucracy had gradually replaced feudalism since mid-Han.
The view that all literati wanted feudalism to come back was not quite true either. The famous Tang writer
Liu Zhongyuan, for example, criticized in his famous prose
Feudal Annotations (Chinese link) that it was feudalism that doomed Zhou dynasty, as it promoted inefficiency, nepotism, etc. It was only when the Qing dynasty came by, the nostalgia for feudalism and rebuilding the China of Confucius and the Sages became overwhelming mainstream, probably as a reaction to the authoritarian literary environment promulgated by the Manchu ruling class.
