Without the concrete retaining wall, the road almost collapsed.

There was no concrete retaining wall and the road almost collapsed. Master Chen urgently made repairs.
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
