I opened a Lu Ji mutton soup. Does it infringe the trademark right of Lu Laoda mutton soup?

Strictly speaking, it is not infringement. So there is nothing to worry about. If you ask this question, it may be near him. It is better to be careful and register a trademark yourself. At the same time, "Luji" has been applied for as a trademark by other companies, so you should be careful of this trademark holder, who is willing to sue you even if he tells you yes. Just find the industrial and commercial bureau. Your brand must be removed. Below is a screenshot of the holder's trademark.
