Passports issued by travel agencies are five years, which is generally enough. Just renew one then.
Passports are easy to handle. Be sure to fill in Thailand when applying. In this way, the procedure is extremely simple and there is not much investigation.
My concern for you is whether the country you are going to is willing to grant you a visa. If you are a tourist passport, it is not as easy as a business passport. Countries such as the United States and Canada can easily refuse visas. It depends on the country you go to.
Besides, the quality guarantee you mentioned should be given. I'm afraid you ran away with your passport and don't have much savings. Generally, 5000 yuan is enough. If they want more from you, you should ask them. I used to work in a travel agency. Hehe, the travel agency where you handed in your passport refunded the deposit to you. Don't worry. Passport is easy to handle, the key is whether the country you are going to give you a visa.
Speak so carefully, I hope I can get everyone's affirmation and choose the answer.
