Tai Chi is a kind of traditional martial arts in China, which has a remarkable function in healthcare. It has been used in many diseases as a complementary theory. The Chinese government attaches much importance to university students' physical and psychological health. However, there is an indisputable fact that the health condition of university students is declining, according to the report of the education ministry of China 2021. Tai Chi is a solid supplement to physical education and how to improve the physical health of university students through Tai Chi is the key to university physical education. This experimental research examines the effectiveness and the differences of two types of Chen Taichi training methods on the physical and psychological health of college students in China. Finally, to evaluate if the Chen Taichi with developed guidelines can improve the college students' physical and psychological health.
The research is a two-group randomized control experiment. The control group (CG) will accept the training of Chen Taichi under the guideline of the "three in one" theory which means the integration of slow circular movements, breath regulation, and concentration or mindfulness. The experimental group (EG) will practice Chen Taichi under relaxation theory which combines the "Body-rotation" and "Relax into Stretch". all other conditions will be kept as same as possible, such as the Chen Taichi routine. An example of one Chen Taichi posture of EG. The arms and legs and the spine should rotate follow the arrow tips in order to cause a stretch reflex slightly. And then, the exerciser should use relaxation skills to eliminate the stretch reflex, such as exhaling, and drop the control of the body. Relax into Stretch: Instant flexibility through mastering muscle tension. The body-rotation levels should be added in steps with the process of practice. It does not need to accompany breathing except the relaxation needs to exhale. Most of the time breathing is common daily.

When the posture needs to open the arms should accompany with "inhale" and when the posture needs to close the arms should accompany with "exhale". Similarly, if the arm is lifting should accompany with inhale, and the put down should accompany with exhale.

Change form baseline mindfulness at 6 weeks and 12 weeks.
Tested by the Five facet mindfulness questionnaire.It is a 39-item and five-point Likert scale instrument. This instrument developed five factors representing mindfulness elements: observing to sensation, describing these internal experiences with words, acting with awareness rather than no "automatic pilot," nonjudging of inner experiences, and nonreactivity to inner experience. The total mindfulness score is calculated by adding all scores of the five factors. Higher scores mark higher levels of mindfulness.

It is a five-point Likert format questionnaire (1=not at all, 5=extremely) that involves a 40-item adjective. The 40-item includes nervousness, anger, tiredness, depression, energy, panic, and self-esteem. Energy and self-esteem represent the upbeat mood, and the other four express the negative mood.

Change form baseline Sleep quality at 6 weeks and 12 weeks.
Tested by The Pittsburgh Sleep Quality Index. The PSQI consists of 19 self-rated questions and five questions rated by the bed partner or roommate. The latter five questions only collect the clinical information, are not tabulated in the scoring of the PSQI. The 19 self-rated questions assess a wide variety of factors relating to sleep quality, including estimates of sleep duration and latency and of the frequency and severity of specific sleep-related problems. These 19 items are categorized into seven component scores, each weighted equally on a 0-3 scale. The seven component scores are then summed to yield a global PSQI score, ranging from 0-21; higher scores indicate worse sleep quality.
