my brief checking, that the term "狀況" in modern usage; the earliest one is in page 102 of 御製詩四集﹒卷七十九, by emperor 乾隆 of 清 dynasty:

the last 4 &amp; 3 characters at the bottom of left most column.

in early 20th century, it's frequency in old hk newspaper:

1900s (8)
1910s (20)
1920s (190)
1930s (505)
1940s (217)
