X (Xuexi) studying visas should be used whenever your main purpose in China is to attend an accredited institution, not necessarily a university.
While studying does not require a specific authorization under Chinese entry regulations (unlike working), your purpose of stay must still be consistent with your visa category. If you are enrolled in a full time program more than a couple days, it is likely that your main purpose is considered study instead of tourism.
In any case, if they are registered with the local education department, (which they are legally required to be), their acceptation certificate can be used for X visas.
FWIW, the Chinese version of the school website looks like a machine translation (a very good one, but still many strange expressions that evoke English syntax). This may be just laziness if the website was developed by non-Chinese native speakers, but nonetheless it is good to ask about their accreditation from the local education bureau ζθ²ε±.

Contrary to some countries, a Chinese tourist visa very likely doesn't allow you to study under it
The FAQ for the visa center reads
What is the major purpose of your visit to China and which is the most appropriate visa category for your application
Major Purpose of Visit | Visa Categories | Description of Visa |
---|---|---|
As a tourist | L | Issued to those who are going to travel to China for tourism. |
As a student | X2 | Issued to those intending to study in China for a period of no more than 180 days |
You are not going there for tourism, and you are studying Chinese
Since the information about what's allowed or not under a visa, is really sparse, as far as I can found, I'd suggest you follow the advice of the school and get a X2 visa
