There are professional tools for making WeChat birthday cards, and I use Yipai Epub6. The following figure shows some greeting card effect cases that can be realized by this tool.
if you make it yourself, you need to learn this tool systematically. You can first look at the case and see what kind of greeting card effect you want to achieve, and then look at the tutorial according to the customer service recommendation in the QQ exchange group. If you don't understand any questions, you can consult the customer service. At present, most functions of this tool are free, so you can learn and have a look.
there is a corresponding tutorial center, where you can learn independently.
