Hi trungtamthuoc.com

   https://www.trungtamthuoc.com and https://trungtamthuoc.com are two different domains.If public key certificates you buy can only protect only one website,you couldn't use https  to visit its sub-domains.To accomplish your requirement,you could  use the Wildcard SSL. 

A Wildcard SSL protects your primary domain and an unlimited number of its subdomains. For example, a single Wildcard Certificate can secure both www.coolexample.com and blog.coolexample.com.  Here is the link ,I hope it will hep you.

Kindly use the below rule for your web.config file.

<rules>
  <rule name="CanonicalHostNameRule1">
    <match url="(.*)" />
      <conditions>
	<add input="{HTTP_HOST}" pattern="^www\.trungtamthuoc\.com$" negate="true" />
      </conditions>
      <action type="Redirect" url="https://www.trungtamthuoc.com/{R:1}" />
  </rule>
  <rule name="Canonical Redirect" enabled="true" stopProcessing="true">
    <match url="^index.html$|^index.htm$|^default.asp$|^default.aspx$|^index.aspx$" /> 
  <action type="Redirect" url="/" />
</rule>
