I think using landscape names is a way, such as Xiangjiang, Yangtze, Dongting, Huangshan, Emei, Lushan, etc. This is a solution. Using plants such as plum, orchid, chrysanthemum, bamboo, etc. is also a solution. If you like wealth, it is not unavoidable to use gold, silver, diamond, jade, etc. as your name. Anyway, it comes down to personal preference.
As for the KTV name, recommendation: 99 KTV (九九, 九九 KTV). 9=Wine, wine and singing go together. Source: Du Fu's poem: To sing in the daytime, one must indulge in alcohol, to keep one's youth company for returning home.
