The five blocks represent the five pile caps. The vertical pen stroke is an "N." The transversely pen stroke is a "工" simple and clear.

My father-in-law came to my house to have tea and chat during the year when I founded the company, I was a little bit unfocused and always looked at the draft. Because the name of the company has picked and it feels OK, but it still lacked the logo, so I can't care about other things. After drinking, I removed the "能" and the two "squares" upper and lower parts in the middle of the "工," so that the logo came out.
