First of all, I will change a flowerpot that looks better than you, either porcelain or plastic. It's better to be a bigger size. After all, it will grow taller and give people more space. Then bury the soil, near the little crookneck you mentioned, to cover this flaw.

If you think the soil is too high for plants, you can buy some stones. Taobao has many things, such as colored stones and pebbles. Decorate them. Choose plant-specific ones, and don't worry about the harmful effects on plants.

Shopping in Taobao, choose a treasure with good store credit and excellent evaluation. Shopping is also a kind of practice. I wish you good luck.
