You made a mistake. You have to ask whether it infringes on whose trademark rights.

Added on November 16:

The biggest risk you face is trademark infringement, not copyright infringement.

According to the query on the Trademark Office website, I found that International Pictures Co., Ltd. is located on the 29th floor of Huahui Center, 28 Marble Road, North Point, Hong Kong. It is located at No. 3-1, Hitotsubashi 2-chome, Chiyoda-ku, Tokyo, Japan. Kaisha Shogakukan respectively holds the "Doraemon" trademark that can claim exclusive trademark rights from you.

In addition, the company you mentioned, Shanghai Aiying Company, may be the owner of certain rights in the copyright of the work, but it is not necessarily the owner of the copyright of the word "Doraemon".

The copyright of these 4 words may belong to Shogakukan Co., Ltd., which published "Doraemon", may belong to the comic author Fujiko F. Fujio, or may belong to the Japanese translation of "Doraemon" A natural human translator, or even a publishing house that publishes the Chinese version of "Doraemon".

Finally, as mentioned above, a small shop may not attract the attention of the rights holder.

And even if the above two right holders notice you, they may not be willing to claim their rights from you. Because rights protection costs money, and you do not necessarily constitute infringement, after all, you are not using the same four words as the trademark.
