What kind of terrier is Lan Xiang?

Lan Xiang refers to a school in Shandong that learns to operate excavators, bulldozers and other series of construction machinery, and is as famous as New Oriental (chef). In recent years, many advertisements in these two schools have flooded, causing netizens to vomit normally.

Excavators, also known as digging machines, are earth-moving machines that use buckets to dig up materials above or below the bearing surface, load them into transport vehicles or unload them into the yard. The materials excavated by excavators are mainly soil, coal, sediments and pre-loosened soil and rocks. Judging from the development of construction machinery in recent years, excavators have developed relatively rapidly, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are working weight (mass), engine power and bucket capacity.
