因项目需求，需要将中文名称转拼音存储，方便查询，考虑到多音字处理，要求最终结果如下：
举例说明：解和景都是多音字(小)
结果：
[xiehejingdushiduoyinzi(xiao), xiehuojingdoushiduoyinzi(xiao), jiehejingdushiduoyinzi(xiao), xieheyingdoushiduoyinzi(xiao), xiehujingdushiduoyinzi(xiao), jiehuoyingdoushiduoyinzi(xiao), jiehujingdoushiduoyinzi(xiao), jiehejingdoushiduoyinzi(xiao), xiehujingdoushiduoyinzi(xiao), jiehuojingdoushiduoyinzi(xiao), xiehaiyingdushiduoyinzi(xiao), xiehejingdoushiduoyinzi(xiao), xiehuyingdushiduoyinzi(xiao), xiehuoyingdoushiduoyinzi(xiao), jiehuoyingdushiduoyinzi(xiao), jiehuyingdushiduoyinzi(xiao), jieheyingdoushiduoyinzi(xiao), jiehuyingdoushiduoyinzi(xiao), jiehuojingdushiduoyinzi(xiao), xiehaiyingdoushiduoyinzi(xiao), jiehaijingdoushiduoyinzi(xiao), jiehaiyingdoushiduoyinzi(xiao), xiehaijingdushiduoyinzi(xiao), xiehuojingdushiduoyinzi(xiao), jieheyingdushiduoyinzi(xiao), jiehaijingdushiduoyinzi(xiao), xieheyingdushiduoyinzi(xiao), jiehujingdushiduoyinzi(xiao), xiehaijingdoushiduoyinzi(xiao), xiehuyingdoushiduoyinzi(xiao), jiehaiyingdushiduoyinzi(xiao), xiehuoyingdushiduoyinzi(xiao)]
