Take my young nephew for example, he always help mother lug the heavy box every time they bought vegetables from the morning fair, which is closely related to parent's guidance and education.

The steel anchor box of the tie ho arch bridge has the characteristics of carrying lug loads and fitting into a small space. This adds to the difficulties in design and production.

I am not digging into boxes in store aisles, but if I discover something Chinese inside a box after I arrive home, I will lug it back to the mall to return it.
