This question could be split into two types of terms: new expressions & old expressions.

For new expressions one could open Google &/or Baidu go to "News" (资讯) and then "Order By Date" (按时间排序).

Other than this I'm not sure if there are any better options.

As for old expressions: there was an answer on here before that mentioned using 漢籍全文資料庫 to find the earliest usage in historical documents.

Again, I don't know if this is the optimal way of doing this.


  • I generally use humanum.arts.cuhk.edu.hk/Lexis/lexi-mf for oracle bone/bronze inscriptions, 王力古漢語字典 for Classical Chinese, and 漢語大詞典 for literary Chinese to near-modern terms. These may not give the earliest usage but will give a very good survey. – dROOOze Dec 29 '19 at 5:47
