According to the traditional customs of China, the place of origin usually refers to a specific city and county, while Jinhua and Lanxi belong to Zhejiang Province, so their place of origin is Jinhua, Zhejiang.
However, in some specific cases, such as filling in some forms or handling some business, there may be higher requirements for the accuracy of the place of origin. At this time, the native places of Lanxi and Jinhua may be different because they are different county-level administrative regions.
So the answer to this question depends on the specific definition and context. If the native place is defined as a specific city and county, then the native places of Lanxi and Jinhua are the same. However, in some specific cases, it may be necessary to accurately determine their native places to cities and counties, and their native places will be different at this time.
