Lidong Zheng was a mother of four, a loving wife, a talented dentist, an entrepreneur, a dear friend, and a child of God. She became a dentist in China and later passed all the dental exams again here in Canada. She had a dream of opening her own dental office and achieved it, growing it quickly in just a few years. While she loved her work, her family was the reason she worked so hard. She loved to travel. She visited China, Spain, the United States, Brazil, Japan, and Guatemala, sometimes for family vacations, and other times to take classes and volunteer as a dentist in low-income communities.

As a mother, she was the one who planned vacations, arranged family events, and bought festive decorations. She took her children camping, to the beach, skiing, sledding, and shopping at the mall. Although work kept her busy, she still made time to watch shows and movies with her daughters during their “girls' movie nights.” She would end calls by saying, “Mommy loves you.” When she missed her daughter, who had gone to university, she would rest in her daughter's room. She would go to the playground with her youngest son, taking him biking when she had free time. Even when she was coughing from lung cancer, she performed a perfect root canal for her eldest daughter. She would pop her head in her oldest son's room to say hi even when she couldn't walk by herself anymore. Later, when she was bedridden, she still asked her sister to bring new bedsheets, pajamas, and leggings from China for her youngest daughter.

As a wife, she was her husband's closest confidante. Together, they went through the hardships of being new immigrants to Canada. They never separated across countries for work. Instead, they stayed together and built a family despite the initial financial challenges, persevering like many immigrant families. She would watch shows and often have late-night chats with her husband. When her husband said he wanted nothing for Christmas and the kids didn’t know what to buy, she always knew the gift he truly needed. She knew her husband and children well and always put her family first.

As a friend, she was kindhearted and generous, offering help with selflessness and warmth. She cherished school reunions and the university friendships she had built decades ago. She comforted her friends when they cried while visiting her. As a daughter, she went to China to care for her father and mourn the loss of her mother, while being there for her siblings. Finally, as a child of God, she listened to sermons in her spare time, especially during her remaining months. She would attend the early 9 a.m. Sunday church service to praise God before work. She also took time to read the Bible with her son. Without hesitation, she sponsored two children in another country, and often prayed for her friends and family.

It is difficult to adequately describe such a capable woman, who was both wise and emotionally present for everyone around her. Lung cancer caused her great pain, yet she battled it bravely for a brutal six months, with the first three months initially misdiagnosed as pneumonia. She passed quietly, but her loss has brought so many tears to those who knew her because she played every role in life so well and meant so much to them. She no longer has to suffer from cancer and has gone to a better place, though her presence is missed greatly. She lived an admirable life, bringing joy and happiness to others. Everyone will miss and never forget the light she brought into our lives.

郑立东是一位四个孩子的母亲，一位慈爱的妻子，一位才华横溢的牙医，一位创业者，一位挚友，也是一位虔诚的信徒。她在中国成为一名牙医，后来又在加拿大通过了所有牙科考试。她一直梦想着拥有自己的牙科诊所，并最终实现了这个梦想，在短短几年内就迅速发展壮大。虽然她热爱自己的工作，但家庭才是她如此努力的动力。她热爱旅行。她曾到访中国、西班牙、美国、巴西、日本和危地马拉，有时是为了家庭度假，有时则是为了参加培训课程，并在低收入社区做义工牙医。

作为一位母亲，她负责规划假期、安排家庭活动，并购买节日装饰品。她带着孩子们去露营、去海滩、滑雪、滑雪橇，以及逛商场。尽管工作繁忙，她仍然会抽出时间与女儿们一起观看电视节目和电影，享受她们的“女孩电影之夜”。她总会在通话结束时说：“妈妈爱你。”当她想念上了大学的女儿时，她会在女儿的房间里休息。她会带小儿子去游乐场，有空的时候还会带他骑自行车。即使她患了肺癌，咳嗽不止，她仍然为大女儿做了完美的根管治疗。即使她已经无法独自行走，她也会时不时地探头到大儿子的房间里打个招呼。后来，当她卧床不起时，她仍然让姐姐从中国给小女儿带回新的床单、睡衣和打底裤。

作为妻子，她是丈夫最亲密的知己。他们一起经历了作为新移民来到加拿大的种种艰辛。他们从未为了工作而远走他乡。相反，他们始终在一起，克服了最初的经济困难，像许多移民家庭一样，坚持不懈地建立起家庭。她会一起看电视，也经常和丈夫深夜长谈。当丈夫说他不需要任何圣诞礼物，孩子们也不知道该买什么时，她总是知道他真正需要的是什么。她深知丈夫和儿女的为人，始终把家庭放在第一位。

作为朋友，她心地善良，慷慨大方，无私而热情地帮助他人。她珍视每一次同学聚会，以及几十年前在大学里建立的友谊。朋友们来访时，她总是给予安慰。作为女儿，她前往中国照顾父亲，哀悼母亲的离世，同时悉心照料兄弟姐妹。作为虔诚的信徒，她利用空闲时间聆听讲道，尤其是在生命的最后几个月。她每周日早上九点都会参加教堂礼拜，在工作前赞美上帝。她还会抽出时间与儿子一起阅读圣经。她毫不犹豫地资助了两个在国外的孩子，并经常为亲朋好友祈祷。

很难用语言来充分描述这样一位才华横溢、智慧过人、又充满爱心的女性。肺癌给她带来了巨大的痛苦，但她勇敢地与病魔抗争了残酷的六个月，其中前三个月还被误诊为肺炎。她平静地离开了人世，但她的离世却让所有认识她的人都泪流满面，因为她在人生中的每一个角色都扮演得如此出色，对他们来说意义非凡。她终于摆脱了癌症的折磨，前往了一个更好的地方，但我们依然无比怀念她。她的一生令人敬佩，她给身边的人带来了欢乐和幸福。每个人都会永远怀念她，永远铭记她带给我们的光芒。
