I know, Tianji app naming technique. I have a friend who works in a naming company. He said that he uses this app to name big clients. He told me that most free naming apps use a very simple program and generally do not include spelling numbers. The Tianji Naming Technique app also includes Chinese naming techniques, so the program is complicated. There is a fee for the Tianji Naming Technique app. . . . My kids were named after this app.
