Why did Wang Laoji change his name to Jiaduobao?

Many years ago, Jiaduobao sold drinks and wanted to have a brand, which would be a good selling point at first.

So, I rented the trademark "Wang Lao Ji" from GPHL.

Later, Wang Lao Ji sold fire, and GPHL thought it was mine, all mine.

Therefore, GPHL took back the brand of "Wang Lao Ji" and took it for himself.

Then, Jiaduobao had to sell it back to Jiaduobao.
