Digging the foundation for a large villa and backfilling the foot beams

Digging the foundation for a large villa and backfilling the foundation beams, but almost caused a big disaster
Hello everyone, I am Master Chen
If you don't work hard when you are young, you will become an excavator when you grow up.
Look up at the bright moon and lower your head at the excavator.
I sleep in spring without waking up, and wake up to excavate the machine.
Master Chen's excavator only operates wax excavators
