    <p>The title is a joke.</p>
    <p>
      But after digging a few holes on the wall, I think I should leave a few
      notes for the future me.

    <ul>
      <li>
        Be careful to choose countersink drill bit (aka mũi khoan).
        <ul>
          <li>
            I pick <strong>wood</strong> type to drill on the wall, and ... it's
            broken :(
          </li>
        </ul>
      </li>
      <li>
        Always wear gloves to protect your hand before touch the drill bit.
        <ul>
          <li>It cut my hand :(</li>
        </ul>
      </li>
    </ul>
