I want to travel to Thailand, so I want to learn Thai. What I want to know is whether there are phonetic symbols like English in Thai, and whether there are five-tone pictures in Japanese.

Thai not only has the upper, middle, lower and left structure of Chinese, but also can be read directly like English, so it is actually very easy to learn. After learning the basics and knowing the pronunciation and rules of each letter, you can read a Thai word according to its pronunciation at any time. Even if you don't know its meaning, you can look it up in the dictionary or ask the Thai people what it means in the future, which is very easy to learn. If you don't know a Chinese word, you can't understand it at all. The most important thing in self-learning a foreign language is interest, and interest can overcome difficulties in learning.

Another digression: if you want to eat pork, you don't have to learn to kill pigs yourself. If you want to travel to Thailand, you don't need to learn Thai. Instead of spending a lot of time and energy on study, it is better to go to Thailand and get in touch with Thai people. After learning the basics, you must have a Thai environment to know your own shortcomings and make progress.
