The Chinese word “古檀” is pronounced as “gǔ tán”. In English, it can be transliterated as “Gu Tan”.
For example, you can say “The ancient Gu Tan tree is very magnificent.”(古老的古檀树非常壮观。) Here, “Gu Tan” is used to refer to the specific object or concept of “古檀”. If you want to use it in other contexts, you can adjust the sentence structure and wording accordingly. Hope this helps!
