I am in Xi 'an and want to travel to Thailand. What is the specific process?

You need to get a visa in China. Although Thailand is a tourist country and can go to landing visa, you can't leave China without a valid visa, so you need to apply for a visa in China.

Applying for a visa in Thailand is very simple. You don't need proof of funds, just your ID card and passport within the validity period. If you queue up at the local consulate, it will cost tens of dollars to 100 yuan (Thailand recently reduced the visa fee to stimulate foreigners' travel, and the visa fee I went to in 2007 was 200 yuan). If you don't have time to queue up, you can find a travel agency, such as Ctrip, and send them the original passport and a copy of relevant documents by courier, or you can go to a local travel agency to earn 20-50 yuan.
