I have been engaged in the production of tombstone statues for a year (not a specialized business, just do it when there is work) for a year. If I specialize in this industry, it will be difficult to earn back the cost. If you can contact several cemeteries or you are already engaged in the tomb industry, if you only use tombstones as a small side job, it is okay to do it as a part-time job. It is difficult to succeed in making tombstones full-time. I checked online and found that there are training courses in Zhejiang, and there are usually one or two in the provincial capital cities. The cost ranges from over 1,000 to 4,000 or 5,000, but everything is actually the same. There is no one that is better or worse, and there are no patents. At present, the effect of tombstone statues is not very good, and the requirements for people are also high. In short, practice makes perfect. It’s not impossible if you meet the conditions I mentioned above. I suggest you do more market research before engaging in this line of work. Is there anyone doing it around me, what is the price, are there many tombstones in cemeteries, are you engaged in other or related things, etc. Don't go in blindly. If you want to learn, you should go online and look it up yourself. Asking questions here will attract a lot of helpers, most of them advertising. What good advice!
