Simplified vs Traditional Chinese Characters
In 1956 and in 1964 China simplified several thousand characters to make learning Chinese less difficult. These simplified characters are now used in China and Singapore, while traditional characters are used in Taiwan, Hong Kong, and many overseas Chinese communities.
In many cases the new forms were ancient characters that had become unnecessarily complex over time. Returning to the original form meant fewer strokes that students had to memorize, and also meant a clearer logical structure of the characters.
In other cases the new simplified characters were popular variant forms that were were widely used due to having fewer strokes and, quite frequently, clearer composition than the more standard form.
Unfortunately, the simplifications did not stop at this point, nor was a more ambitious effort made to systematically clarify the phonetic and semantic information in the characters. Instead, a large number of more questionable simplifications were made, sometimes by conflating different characters, sometimes by adopting variant or script forms that had fewer strokes than the standard form, and sometimes by creating completely new forms with fewer strokes. The phonetic and semantic information in the characters was sometimes improved on but often degraded, while a large number of inconsistencies between characters were created, undermining the goal of making Chinese characters easier to learn.

Due to the political environment of the time, it was dangerous for scholars to criticize the inconsistencies that were being created by simplification. While their problems can now be discussed more openly, at this point the simplified characters are so widely used that there is little hope that the inconsistencies will be fixed or that China will return to use of traditional characters.
