Differences between 喜欢, 要, and 想? Could someone explain to explain me the difference between the three verbs
喜欢 (xihuan), 要 (yao), and 想 (xiang)?


我喜欢喝一杯啤酒。 (wo xihuan he yi bei pi jiu)
我要喝一杯啤酒。 (wo yao he yi bei pi jiu)
我想喝一杯啤酒。 (wo xiang he yi bei pi jiu)


When do I have to use it?
喜欢(xi3 huan1) means to like

要(yao4) tends to realize the action

想(xiang3) means to want, but you don't have to realize it. Sometimes it is just an expression of your desire.
