Has it ever been so dark you couldn't see anything at all, not even your own hand in front of your face? In Chinese there's a very similar expression. In the spirit of Halloween,

let's get a bit dark for this minisode, and upgrade our Chinese from 太暗了 to 暗得伸手不见五指吧！

伸手不见五指 （Shēnshǒu bùjiàn wǔzhǐ）

Can't see your hand in front of your face

Vicky's Translation:

所以你在上海的时候，曾经去到过一个很有意思的咖啡馆。这个咖啡馆的名字很有意思，叫做黑暗咖啡馆。它其实是一个餐馆，然后你进去了以后，发现里面伸手不见五指。那人怎么吃饭呢？

Suǒyǐ nǐ zài Shànghǎi de shíhòu, céngjīng qù

So when you were in Shanghai, you went to a very interesting cafe. The name of this cafe is also very interesting - it was called Dark Cafe. It is actually a restaurant, and when you go in, you find that it is pitch dark inside. How do people eat?

所以你吃的是西餐，然后你看不见，什么都看不见，只能摸着吃。那这个餐馆的服务员，他们的工作很难做吧？

Suǒyǐ nǐ chī de shì xīcān, ránhòu nǐ kàn bùjiàn,

So you eat Western food, and you can't see anything, you can only eat by touch. Then the waiters in this restaurant, their job is difficult, right?

这个很有意思，就是说餐馆里的服务生都是盲人，所以他们对于这个工作环境很熟悉，然后对于顾客来说，就是一个人搭在另外一个人的肩膀上，像开一辆火车一样，把每个客人带到自己的位置上。听起来很有意思，我也很期待，想去这样一家餐厅去体验一下.

This is very interesting. The waiters in the restaurant are all blind, so they are very familiar with the working environment. For the customers, one person puts his hand on the other person's shoulders like a train and are led to their seats. It sounds very interesting. I want to go to such a restaurant to experience it.
