Why did the feudal monarchy system be abolished and the western system and ideas were introduced in the Republic of China, but the costumes were still very traditional and lived in the Republic of China?

To accept western political thoughts is not to abolish the national traditions and westernize them in an all-round way. It is not possible for China's traditions for thousands of years to change immediately after changing the feudal monarchy. It is not like the establishment of the Magic Republic of China and the proliferation of high-rise buildings with western suits and dresses all over the street. It takes a process to change.
