Pls answer these Chinese proverbs

1. Only a vessel that is half-full can be shaken
半瓶子醋好晃蕩
半瓶子醋：醋沒裝滿瓶子。喻對某種知識，某種技藝一知半解。晃蕩：搖動。喻不穩當。醋瓶子沒裝滿醋，容易搖動。藉喻知識淺薄的人，喜歡自己吹噓。

2. When you paint a dragon,you paint his scales, not his bone; when you see a man,you see his face,not his heart
畫龍畫虎難畫骨，知人口面不知心
3. He who rides the tiger finds it difficult to dismount
騎虎難下

希望幫到你！
