In Chinese, there are a lot of ways to say washroom. Like ‘洗手间、厕所、卫生间’and so on. The ones Crystal often used are ‘洗手间’and ’卫生间’.‘洗手间(xi3 shou3 jian1)’ is like washroom in English, literally meaning ‘the room to wash hands’.’卫生间(wei4 sheng1 jian1)’’s literal meaning is hygiene room. The usage of these two is almost equally as frequent. The other one is ‘厕所(ce4 suo3)’, like the toilet in English. But I don't use it so often, to girls it's coarse. OK, let's learn this Chinese together! ‘Excuse me, Where's the washroom?’-“请问，洗手间在哪儿？”’请问(qǐng wèn)’ is often used when you ask questions to others—for example, asking for directions, asking the time. It's like Excuse me in English. “洗手间(xǐ shǒu jiān)”means toilet, “洗手间”. In“在哪儿(zài nǎr)”, “在” means ‘at’, “哪儿“means where “在哪儿” is “where is”。 So, “Excuse me, where is washroom” in Chinese is ”请问，洗手间在哪儿(qǐng wèn, xǐ shǒu jiān zài nǎr?)
