#### 自行处理表单数据
使用 `Form.create` 处理后的表单具有自动收集数据并校验的功能，但如果您不需要这个功能，或者默认的行为无法满足业务需求，可以选择不使用 `Form.create` 并自行处理数据。

#### Handle Form Data Manually
`Form.create` will collect and validate form data automatically. But if you don't need this feature or the default behaviour cannot satisfy your business, you can drop `Form.create` and handle form data manually.
