Before the 1970s, although Chinese medicine had accumulated considerable experience and achievements in the process of scientization, its theory was still kept in the framework of traditional Chinese medicine without further forming a complete set of scientific theories with systematic and empirical evidence. After the founding of the hospital's Department of Chinese Medicine in 1970, there have been remarkable achievements in the modernization or scientization of Chinese medicine.

Since 2001, director Chin-ming Huang of Chinese internal medicine has begun to develop Huang's pulse wave instrument, which was granted a category control number by the Department of Health in 2012. Its functions include: 1) instant analysis of pulse condition, time domain, and high and low frequency spectra; 2) measurement of derived functions and radial artery augmentation indices, and 3) image teaching for 28 kinds of pulse condition. It is able to fully present the characteristics of pulse manifestation—position, number, shape, and potential—so as to assist  Chinese medicine clinical pulse feeling and pulse diagnosis teaching.

The development of the hospital's auscultation-olfaction instrument began in 1995. It was professor Heng-hung Chang who proposed the original idea and worked with professor Chuang-chien Chiu of automatic control engineering at Feng Chia University. Using speech analysis technology, they completed the speech analysis of qi deficiency, yin deficiency, yang deficiency, and blood deficiency, so that Chinese medicine diagnosis could be further developed in terms of scientization and modernization.

The development of the tongue diagnosis instrument is also a diagnostic indicator of scientific and objective Chinese medicine. The instrument is derived from dean Heng-hung Chang's ideation and was jointly developed by professor Chien-chung Chen, director Hung-jen Lin, and professor I-wu Chiang of Sun Yat-Sen University more than a decade ago. In recent years, with the collaboration between dean Heng-hung Chang and professor Lun-chien Lo, the instrument has been continuously updated to be closer to the use and interpretation by clinicians of Chinese medicine. Moreover, they developed a computer-aided tongue diagnosis and interpretation system to push the Chinese medicine diagnostic apparatus to a higher level.

Through observational studies on scientific pulse feeling, auscultation and olfaction, and tongue observation, it set up a universal platform for Chinese and Western medicine to diagnose diseases in patients via science mapping.
