Chinese emperors turned their backs to the north and their imperial palaces traditionally faced south

Chinese emperors turned their backs to the north and their imperial palaces traditionally faced south, is a true statement.

Explanation:

The Chinese emperors were imperialistic and to show their superiority among other officials and common people, they would sit facing the south with their back to the north.

The other officials were seated on the east and west side of the emperor depending upon their ranks. The highest ranked officials were seated at the north near the emperor and as the rank decreases, the lowest ranked were seated in the southern part of the palace. The audience or the people also thronged at the south.

This arrangement is done so that whoever comes to respect the emperor will prostrate facing the north. This is to create a sense of supremacy where the emperor is considered as the North Star with other stars (officials and people) surrounding him at the central axis.  

The Chinese believed a lot in directions and its effect on life. Accordingly, south was considered to be a source of good fortune, wealth, warmth, and light. Imperial palaces were faced south to evade evil happenings also.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
