Answer:
The Constitution enumerates a great many powers of Congress, ranging from seemingly major powers, such as the powers to regulate interstate and foreign commerce, to seemingly more minor powers, such as the power to establish post offices and post roads. But there are many powers that most people, today or in 1788 (when the Constitution was ratified), would expect Congress to exercise that are not part of those enumerations. The Constitution assumes that there will be federal departments, offices, and officers, but no clause expressly gives Congress power to create them. Congress is given specific power to punish counterfeiting and piracy, but there is no explicit general authorization to provide criminal—or civil – penalties for violating federal law. Several constitutional provisions give Congress substantial authority over the nation’s finances, but no clause discusses a national bank or federal corporations.

Explanation:
What demonstrates that china stopped trading with other areas of the world and became isolated due to fear of cultural change is that "China took this action at the demand of Confucian scholars who tired of barbarian contact".
During this period, the Chinese Scholars felt that the people of their outside regions were uncultured and barbaric hence they must stay away from them so they won't affect their unique way of life.
