Tips

发脾气 (fā píqi) = to lose one's temper. 脾气好 = good-tempered. 脾气不好/脾气大 = bad-tempered. 闹脾气 (nào píqi) = to throw a tantrum (often about children).
culture
The connection to the spleen (脾) comes from traditional Chinese medicine, where the spleen is linked to worry and pensiveness. An imbalanced spleen leads to irritability - hence 'spleen qi' became 'temper.'
