stubborn; hardheaded
Rare expression meaning obstinate or unyielding. The reading じょうがこわい is unusual; 情 is normally read じょう in compounds, but the whole phrase is not common in modern Japanese.
「情が強い」は、頑固で人の言うことを聞かない様子を表す古い言い回しだ。
「情が強い」 is an old expression describing someone stubborn who won't listen to others.
The phrase combines 情 (じょう, 'feelings, emotions') with 強い (こわい, 'strong, tough'). The exact historical derivation is uncertain; it may have originally described someone with strong, unyielding emotions, later shifting to mean stubborn.
