Okay kiddo, let me explain to you what "think think and ah tsai" means. Have you ever heard the saying "think before you act?" Well, "think think" is kind of like that. It means that you should take some time to think about your actions and decisions before you do anything. It's always better to be confident in your choices and weigh the consequences of your actions.
Now, "ah tsai" is a bit different. In Chinese culture, "ah tsai" means to be mindful of the small things around you. It's like paying attention to the little details in life and being grateful for them. So together, "think think and ah tsai" means that you should take time to think carefully before you do anything, and also be mindful of the little things around you. It's a good way to live your life!
