In the early 1990s, the zhu army gave priority to the concept of "a car doctor", actively promoting research and development of auto diagnostic techniques, conducting hundreds of lectures on "a car failure diagnosis" in 108 cities in 25 provinces of the country, training in tens of thousands of auto maintenance enterprises and training nearly 200,000 auto mechanics。

Compiled and co-authored a manual on electrical engine failure code, a manual on solar car maintenance, new vehicle technologies and structures, practical pollution control techniques for vehicle discharges, english motor engineering dictionary, electrical circuit wave-form analysis for electric motors, technical guidance on vehicle emission management, training materials for auto mechanics, vehicle failure diagnosis methods, etc. A series of lectures and technical articles in the national automobile maintenance industry were produced on the principles and maintenance of electrical engines, on the engineering and maintenance of motors, on the principles and maintenance of automatic transformers, on the analysis of waveforms of motors, on the introduction of motor analysers' products, on the application of engine analysers, on the analysis of oxygen sensors, on the application of car oscillators, on the equipment and use of vehicle maintenance detection equipment, and on the principles and maintenance of anti-sliding systems and on automobiles。

The zhu army has successfully developed a module on "technology in automobile practical training" and published in people's transport press the "physical training materials on common maintenance projects for automobile engines" (including 2 dvd cd-roms), "physicals on common maintenance projects for car chassis" (up and down) (including 2 dvd cd-roms), "physicals on common maintenance projects for automobile appliances" (including 1 dvd cd-roms) etc. For two consecutive years, 2007 and 2008, he was the president of the national university of automotive profession skills。
