There are many places to check duplicate names now, but the most accurate and authoritative one should be the entrance of official household registration management. The websites with duplicate names in the above provinces can be searched directly by clicking in, so it is relatively long, and some websites need to be registered to query.
In addition, official website can only search for names with the same name and surname, so when searching for names with the same name and surname, all surnames with a population above 10 can be found, which accounts for about 44. 1% of the total population of China. For example, if there are 10 people named "Wei" and there are 1.5 million, then there may be about 3 million in the whole country.
