Wrong. .
Singha [pronounced Sing] means Lion thus Sing-To means great Lion. The word for Tiger is Sua [pronounced Su-ea].
The tiger is not a symbol of strength in Thailand, cuz they have the Elephant. Now, what animal, except humans, can stand up to a full grown elephant?
Lion [Sing] is the symbol of authority in Thailand thus many have it in their names to represent authority, not strength. As for Tiger, not a lot of Thai/Lao people have it in their names. Strangely, not alot of people have elephant in their as well. It sounds ok, "Kochasan", oh well...
As for you Singhay, where you from? Maybe you're from Laos?
