What platform is reliable for plumbers to find jobs?

If you want to find a job suitable for plumbers or other agricultural workers, I recommend you to use Jigongjia APP, which has national patent works and is specially developed for our migrant workers. A friend of mine used this APP before, and he really helped him find a lot of jobs. Before, he was very confused about finding a job, so he had to rely on friends to introduce him. If it is not introduced by a friend, he doesn't know what to do, and he is always easy to be cheated. A friend said that although Jigong's APP sometimes calls, the work will be full, and a phone call will be made in vain, but after all, there are many people who use it and make calls, and it may be enough to work late. But on the whole, you can still find a good job by playing a few more games. Now my friends are still using this software. Recently, the APP seems to be in the most clothes-making activity. I think he is fighting. He received a free dress and invited me to go. I haven't started yet.
