I transferred a trademark "Timic" at the end of last year. Due to negligence at the time, I used the car seat cushion subcategory in 1202, but the subcategory of the trademark 1202 does not have this category. I would like to ask Can I apply to expand this subcategory?

The "Trademark Law" stipulates that a registered trademark needs to be used on other goods of the same category, and a separate registration application should be submitted. The person who left the message can submit a new trademark registration application, and the Trademark Office will review it in accordance with regulations

Our company is Shanghai Wenlida Power Electronics Co., Ltd. and applied for trademark registration yesterday on April 19, 2018. The application number is 30364767. I found an error in the registration category and want to change it. Can teachers please apply for a withdrawal, refund and re-registration?

Can be withdrawn but cannot be refunded.

25963702 is a trademark with multiple categories, and now 21 categories of trademarks are to be transferred. How should I proceed?

When applying for trademark transfer as mentioned above, all categories under the application number need to be transferred together. For the application procedures and required materials, please see "China Trademark Network - Trademark Application Guide - Transfer Application".
