Dear Hoang Chu,
You can change or remove some positions in the layout file.
Example: main-left-right.xml
Please go to "templates\sj_health\layouts\main-left-right.xml", finding:
<header html5tag="header" order="2" id="yt_header" autosize="0">
<positions>
<position class="span2" data-normal="span3" data-tablet="span4" data-stablet="span4" type="feature" style="ytmod">@logo</position>
<position class="span3" data-normal="span4" data-tablet="span4" data-stablet="span4" type="modules" style="ytmod">top1</position>
<position class="span2" data-normal="span4" data-tablet="span4" data-stablet="span4" type="modules" style="ytmod">top2</position>
<position class="span3" data-normal="span4" data-tablet="span4" data-stablet="span4" data-mobile="hidden" style="ytmod" type="modules">top3</position>
