Which company is better at learning excavators and what does it mean?

Today I saw a story on NetEase for the first time. There was a sentence at the end: "The only thing left is to learn the excavator technology. Please tell me which company is better?"? I was very confused at the time. After searching on Baidu, I couldn't find the answer. Later, I heard a colleague answer as follows:

How to use "Which company is best for learning excavator technology"? As follows----

(1) Shui Tie (Shui Tie) that often appears on NetEase That is, it is often used in replies whose content and opinions have nothing to do with the original topic). First, tell a story, and then suddenly say "Which company is better at learning excavator technology?", which means "Which company is better at learning excavator technology?" It's his catchphrase, and he often says it. This sentence has nothing to do with the story he just told. The story he just told was entirely to attract everyone's attention, and finally told a nonsense sentence to tease everyone. He said this sentence "Which company is better at learning excavator technology" without any connotation, just for fun! Just like suddenly saying an advertising slogan during a normal chat!

(2) also appears frequently on NetEase, and its usage is the same as above. You can understand that he is advertising for Shandong Lanxiang Technical School, or you can satirize the falsehood of this advertisement.

(3) It means that the technology from Lanxiang Technical School is the strongest.

(4) My personal guess is: Which company is better at learning excavator technology? ?The excavator has two big wheels and one force arm, which is similar to a man’s genitals. Excavator technology refers to the technology of men doing that, ML technology. When a man asks this, it means that his sexual ability is weak and he wants to improve it, or he wants to practice more; when a woman asks this, it means that she wants to find a strong man to accompany her.

The above explanation is for reference only. NetEase commenters are so stupid that they can’t tell the real meaning and start following the trend. There is currently no official explanation! At least many netizens believe that the purpose of using this sentence is not to advertise Shandong Lanxiang.
