Teacher Liu, I've recently been seeing a lot of people online recommending a Chinese learning app, so I downloaded it.

How is it? Is it really as good as the videos say?

Not really. Many features require payment, and the content isn't as interesting as they claimed.

Some of those videos are sponsored by the company. They look like they're from ordinary users, but they're actually advertisements.

I see. There are also some accounts that keep saying this app is amazing.

Those accounts may also be connected to the company, so don't just look at positive reviews. You should also read genuine reviews.

It seems I can't believe every recommendation I see online. Next time I see this kind of video, I'll first think about whether it's actually an ad.

Exactly. Don't rush to believe it. Treat it as an advertisement first, then decide whether to use it based on your own needs.
