To be able to read and write, one must memorize about 2,000 characters, so it will take you more time to learn about Chinese characters through many articles and regularly talking with native speakers. On the other hand, Chinese has many similar tones, which makes it easy to confuse and misunderstand the true meaning of the word.

For example, "mai" with a falling tone means “sell” (mái卖) but when pronounced with a tone that falls and then rises, it means “buy” (măi买). But instead, Chinese grammar is not difficult and very easy to understand.

Thai has 44 consonants, plus 9 vowels written in 14 different ways. 16 of the 44 consonants are unnecessary because only 28 are basic, the rest are compound consonants. In addition, there are 4 accent marks (mean, rough, tri, and chop-ta-wa), the second difficult point of Thai is that Thai texts are read from left to right, and between words in the text.
