Why does someone in our apartment complex yell something like "dòuhé" at around 8am?

Question

Basically every morning at around 8am, there's someone outside my apartment in Beijing yelling something that sounds like dòuhé, which is audible in everyone's apartment.

I managed to record him saying it: here.

I have no idea what this means (I can't find it in Pleco). He might be selling something (like breakfast), or it might be related to garbage collection.

Okay, I went down to his van this morning and took a photo of what's inside:

Answer 1

if i heard right, he was yelling 豆腐。I think he was selling tofu. Some Chinese northerners especially when shouting for selling 豆腐，the pronunciation is sometimes changed from "doufu" to "doufe".

edited: yes you see, it's tofu. I think this website can help you: https://en.wikipedia.org/wiki/Tofu

the weird pronunciation is, as I said before, just because of the northern accent. I think the reason may be "doufe" is easier to be loud than "doufu". They must make sure more people can hear he is selling something 😄

Answer 2

After listening to the recording, It sounds more like 早飯 (breakfast) /Zǎofàn/

To confirm my theory, please go out at 8:00 AM and find the street vendor around your apartment and see what he's selling

It doesn't sound like 豆汁 /Dòuzhī/ Douzhi as I previously thought, although 豆汁 which is a breakfast food unique to Beijing City does make very good sense

It also sounds like 豆花 (Douhua) but 豆花 is called 豆腐腦 in the north
