Hmm, the user is asking about what championship the Chinese team just won at the Swimming World Championships. Let me carefully analyze the search results I've received.

Looking through the search results, I can see multiple championship wins by Chinese teams across different events and dates. The most recent wins mentioned include:

• On July 29th, Chinese divers won gold in women's 3m synchro and men's 10m synchro 3
• On July 25th, China won gold in artistic swimming team technical routine 2
• On July 22nd, China won gold in artistic swimming team technical optional 1
• On July 20th, China won gold in artistic swimming team free routine 6
• On July 19th, Xu Huiyan won gold in women's solo technical routine 8

The user didn't specify a particular date, so I should consider what might be considered "just" won. The search results from July 29th about the diving events appear first in the results list, but the artistic swimming events from July 25th and 22nd are also prominently featured.

Since the user asked about "just" won and there are multiple recent championships, I'll list the most recent significant wins while noting that artistic swimming (花样游泳) has been particularly successful with multiple golds. The diving team's double gold on July 29th is also very recent.

I should present this information clearly, highlighting the multiple championships China has secured in the ongoing World Championships.
