Ms. Cheng passed away at home on January 14, 2009 for gastric cancer. She was 68. Puyuma Association held a memorial ceremony for Ms. Cheng in the afternoon of January 22. Many people gathered at the ceremony including her family members, friends and relatives, and students. They all came to pay her tribute.
Ms. Cheng was the fourth child at home. Sisters call her 3rd Sister. Friends as close as siblings call her Sister Cheng.
　　The mood of the ceremony was sad and solemn. A few guests came to the podium to express their feelings about Ms. Cheng. They all shared the same admiration to Ms. Cheng’s teaching contributions in promoting Puyuma language. After completing her last 120-hour language networks activity in 2008, she left this world peacefully.
　　Even in her final stage of gastric cancer, Ms. Cheng still insisted on continuing her share to work for the language promotion. Her bravery and perseverance touch every teacher who comes to her assistance in teaching no matter how far they need to travel, some from Kaohsiung and some from Taitung. They have only one goal, to continue teaching their language to generations to come.
　　Those who came to the podium to speak all mentioned that Ms. Cheng would prepare breakfast in person for every teacher who came all the way to teach. She dragged her weak and skeleton body to bring breakfast to classroom and warmly chat with teacher and students. Every teacher is fully touched by her heartfelt warmth.

　　Ms. Cheng’s contributions prior to her death in promoting indigenous language are obvious to all. She was the first teacher to obtain the Certification of Indigenous Language and started to teach the language in elementary schools in Taipei County. There was a time when she had to teach in five elementary schools on a weekly schedule. Far or near she was willing to go. Even there was only one student learning Puyuma language in the entire school, she would go and would not give up the chance. Her goal is to let more children to accept mother tongue education and let parents to support their children in study as education can improve their family condition.
Ms. Cheng had hosted many indigenous language learning camps and had been judge for many activities or competitions. She had very high self expectation. For every mission, she prepared herself carefully and always made the best out of it. It is obvious to see how hard she worked from the arrangement of teachers and programs for each learning camp.
　　Since there aren’t too many Puyuma language teachers, Ms. Cheng often invited teachers located in Taitung to come to Taipei to assist. She showed great respect and warmth to those teachers coming from afar. Not only did she entertain them at home, but she also prepared meals for them. Ms. Cheng treated them like sisters.
