Riku introduced an online family tree creation tool called Genoom, which I tried and found quite good. Later, I discovered another online family tree management website, geni.com, which is even better than Genoom in many ways. Geni.com is an online family tree creation tool built using AJAX and Flash technology. The Flash interface makes it very convenient and fast to create a family tree chart, supporting zooming so that it doesn't become difficult to manage even when there are too many family members. Moreover, it fully supports Chinese. In addition to creating regular tree-structured charts, it can also generate personal cards for each member, display member locations on a map, provide a family member list, extended cards, family photo albums, and discussion lists among other features. Additionally, the family tree can be browsed in various ways such as Tree | List | Index | Calendar | Map | Discussion, making its operation more diverse and user-friendly.
