How to obtain the administrative boundary at the township level of the map

I want to use echarts to do a graphic display from county to town. I tried Baidu map api, sky map. The boundaries of administrative maps can only be found at the county, district level, and township administrative boundaries. Can any Daniel tell me how to find the administrative boundary of the township? thank you here!
