    Hello Ploy,
    I like this page very much.
    Thank you for sharing.
    If you allow, I like to make two tiny comments:
    – You use the word “alphabet”. In western language “alphabet” means the complete collection of characters. It stems from the Greek word-sequence “alpha-beta-…”, which are the two first characters. In Thai that would be “กอ-ขอ-…”. So, here it would be more correct to write about a “character”, if you mean only a single one.
    – f or the pairings of high-class and low-class characters I was missing the “por”-group and the “for”-group. I figured it out myself, but maybe you like to update the webpage for the other students.
    Thank you again for this nice webpage.
    I whish you good luck with your business.

      And for the Pairing of High class and Low class they are just some examples. So, That’s why I did not show you guys all the pairings.

      Thank you again.
      I wish you all the best!
