A three-character brand name can add many words. What you can add depends on what industry you want to use. You have to see if there are any similar trademarks before you can tell you how to add words. If no one is registered in Ai Shan, you can use the trademark of Ai Shan's model according to whether anyone is registered in X Mountain. All this needs to be audited according to your industry, so you can know whether you can add this word, so if you want to know what is appropriate, you still need to provide your industry, so as to give you better name suggestions.
