This is the Xinhua Dictionary of 1953, its main role was to promote national literacy,The traditional Chinese characters are in brackets.
This is the Xinhua Dictionary of 2020, which is a literacy reference book for primary school students, still have traditional Chinese characters.
You will find that only part of Chinese characters have different between traditional and simplified.
Using Xinhua Dictionary is already the primary requirement of literacy, I am a calligraphy lover, my practice involving traditional Chinese characters and more classical Chinese characters 😉 You know,even you never meet this character, as long as you can use simplified Chinese , you can also understand it’s meaning.
