1. A trick to memorize and distinguish between flat and warped tongues is to just remember all the words for flat tongue! Among Chinese characters, there are far fewer characters with flat tongue sounds than characters with raised tongue sounds, so during practice we only need to remember the characters with the same sound as flat tongue sounds, and the others are with raised tongue sounds.
2. Although we have the above tips to memorize and distinguish flat and raised tongue characters, we still need the process of memory and proficiency. Through the practice of the current game, we can reach the point where we can judge whether a word is flat or raised without thinking, and achieve the "muscle memory" of the brain.
3. After we can distinguish the flat and curled tongues of words by playing games, we still need to distinguish and practice the flat and tilted tongues of words in an interesting way during daily speaking and reading. Because single words are used in game practice, we may not be able to react well once the words are put into words or sentences, so we need to practice for a period of time in daily life.
4. According to the memory curve, if we find that we have forgotten some words after memorizing them for a period of time, we can consolidate them through the dictionary or come back to play games.
5. Due to the development time, the functions of the current game are not very complete, and there may be many shortcomings. If you have any questions or other better suggestions in the game, you can leave a message in the comments.
