Recently, I met a company in xi 'an: Shaanxi Hancheng Coal Industry Co., Ltd. wanted to purchase our goods and asked our company to go to Xi 'an for an interview and sign a contract. Is it credible?

I don't know the specific contact process. If you really want to do it, first go to official website, Shaanxi Provincial State Taxation Bureau to check whether there is this company. If so, send a reliable person from Xi 'an or Hancheng to their company for an unannounced visit, and then talk about it first after it is confirmed. Don't invite people to eat or drink. It's not necessary. Now all the coal mines in Shaanxi are in arrears with the customers of coal companies in this system, and it is useless to spend money.
