You can't apply a formControlNamedirective to an strongtag. It must be applied on a form field tag (select, input, textarea) or a custom component that implements the CustomValueAccessorinterface.
您不能将formControlName指令应用于strong标签。它必须应用于表单字段标记（select、input、textarea）或实现该CustomValueAccessor接口的自定义组件。

You should use formControlName="sNo"on an input and not on a strong
您应该formControlName="sNo"在输入上使用而不是在输入上使用strong
