Hello Chuanyi,
Unfortunately, the image is not properly attached. You can try uploading it to other image sharing platforms, for example:

If you want to put several tasks on the same row, you can use the Split Tasks feature:

Here are examples of how it works:

If you mean something different, please, upload the image again or describe your question with more details.
