A confusing word (and an important and often-repeated one) in this text might be 安. We know this word most commonly means “peace”. But the author keeps saying 安电话. This does not, contrary to appearances, mean “peace phone”. In this case, 安 is the shorter version of 安装 ān zhuāng, meaning “to install”. So, 安电话 means “to install a phone”.
There are also a few proper names in here, which we’ll point out early: 燃燃 is the author’s name, when the author is addressed by a loved one (typically who is older than them). 李燃 is the author’s actual full name. You can see from this that family members and close friends will sometimes take a Chinese person’s given name (which as we know, comes last, and in this case is 燃), and double it as a form of endearment. So 李燃 becomes 燃燃 to close friends and family. This isn’t always the case but you’ll see it a lot. It is inappropriate to address a Chinese person this way unless you know them very well, and you should never address an elder this way. It’s considered very cutesy. Another proper name is 王钰涵 wáng yù hán, the author’s best friend mentioned in passing.
In several instances, the author also mentions the “滋味” of using a phone. 滋味 literally means “flavor” or “taste” (noun). In English, we’d probably substitute the word “feeling”.
And a final grammar note on the phrase: 像是没见过电话似的. Pay attention to the 像 – it’s attached to the 似的 at the end. Together, wrapped around a phrase, these characters mean “as if…” or “like…”. This phrase means “… as if I had never seen a phone before”.
