Unfortunately, I can't simply trust PRs that just have several approvals.

Several times it has happened that there are PRs with 3, 5 or more approvals, probably because the description is appealing, but when I check the PRs, they are actually broken, have a bug, or don't solve the problem they claim to solve. 😅

你會看到自動產生的 API 文件，包含來自所有子模組的路徑，使用正確的路徑（與前綴）與正確的標籤：

## 以不同的 `prefix` 多次納入同一個 router { #include-the-same-router-multiple-times-with-different-prefix }

你也可以用不同的前綴，對同一個 router 多次呼叫 `.include_router()`。

例如，這對於在不同前綴下提供相同的 API 很有用，如 `/api/v1` 與 `/api/latest`。

這是進階用法，你可能不會需要，但若有需要它就在那裡。
