What are the three principles of the people"? Are these realistic in China? How about in today's world?

What are the three principles of the people?

The three principles of the people are :nationalism, democracy, and the livelihood of the people.

This ideology was developed by  Sun Yat-sen to create  prosperous nation.

Are these realistic in China?

No.  China has a massive authoritarian power structure, in which the government owned almost all the resources in the country.  The people do not obtain the right to free election, which do not fulfill the 'Democracy' Criteria from the three principles.

How about in today's world?

Absolutely. Those three principles are generally popular among the citizens, it should not be difficult to achieve.

Probably the biggest challenge for any other country in the world would be fulfilling livelihood of the people.

But it can be solved by having emphatic understanding toward the hardship that felt by our fellow citizens.
