囗 (wéi) is Kangxi radical no. 31, “enclosure”. In this form it is written with 3 strokes.
The closed frame 囗 (wéi) surrounds the rest of the character: borders, countries, gardens, things that are enclosed.
The characters range from 5 to 11 strokes. 4 of them already appear in HSK 3.0 levels 1–2, and 2 have a full word page of their own.
Good ones to start with: 四 (sì) four, 回 (huí) return / go back, 国 (guó) country, 因 (yīn) cause.
