路牌 [lù pái]

I think that's the correct word.

大家好！我在国防语言学院学习中文。因为我快要毕业，并且我快要考DLPT5，我要对你们替一个问题：在一个很短的期间以内，最好的词汇学法是哪一个？我的意思就是，我要很快的提高我的中文词汇。怎么办啊？

A joke on a Chinese site lists 40 Chinesewords for "wife" and 27 for "husband."  Check it out:

I'm sure you hard-working people are fed up with us wanting more features. ChinesePod is awesome, but there's a slight thing that would make it even more so.

Is it possible to enable the possibility of adding entire sentences to your vocab? As it is now, you can add words and sometimes phrases, but there are also lots of complete sentences with every lesson. Sometimes it's great to be able to review entire sentences at a time with flashcards, so you can get a lot of words reviewed at the same time, as well as seeing them in context and getting some grammatic patterns down.

I'm not a programmer, so when I say it doesn't seem like it would be much of a hassle, that doesn't mean much. If it is, just disregard this. But if it's not, it would really help me, and maybe others, to get reading practice and grammar training.

Just searched all ChinesePod lessons for

•     劳驾 = láojià = excuse me

but it was never used - why?

It's an HSK Beginner vocab item!
