The protest in China was not successful because of lack of support by the people and the brutal response from the government.

Explanation:

The Tiananmen Square pretests are known all over the world, unfortunately not because of good reasons. While these protests were very inspiring for the people in the neighboring countries of China and led to success when it came to the demands of the people, that was not the case in China.

The reasons why it was not successful in China are that when compared to the population of the country, it was actually very few people that were protesting, while the majority didn't offered support and were standing behind the government. Also, the government was very quick and brutal in its reaction, sending the military and tanks to destroy the protests, and it was very effective. Not just that the protests were destroyed, but also the people that maybe wanted to support them were terrified to death and didn't dear because of the consequences.
