Shiquan converted to Taoism in 2015. "I have never been the Type A student, nor the type who acquired a high academic degree. I don't have any specialty or a clever mind. But by following my master Liang, I can feel myself improving, in studying knowledge and socializing with people," Shiquan said. "It's enough for us as long as we run our Taoist rites well, complete things we are obliged to do. I don't know how to say pretty words, but only know one simple thing, which is to always give a hand to those who are in need." REUTERS/Tingshu Wang SEARCH "TAOISM TINGSHU" FOR THIS STORY.
