At first, I had no knowledge about Indonesians, so I was quite anxious. However, I soon realized that they were serious about their work and were enthusiastic about it, so I was relieved. For example, when I arrived at the site before 8 o'clock, they opened the drawings and looked at them, even though they couldn't understand them yet. They are trying to prepare in advance so that the work of the day will go smoothly. As expected, because they work hard every day on the work in front of them, they grew quickly, and after three months, I think they were at a level where they could be called a force. There was only one thing I was careful about, which was greetings at the site. If you can do that, you will be loved by people in other positions at the site. Now they have grown into reliable personnel who can be trusted to be entrusted with the site with confidence, so it is really helpful. They are all reliable people.
