**The combination with wechat applet is natural
The user experience is also the most smooth**
So it’s not difficult to understand why
“Tiantiantong” such an excellent small program
Tencent location service will be the first choice for map development.
At present, Tencent location service has

From service API, basic map component
Personalized layer, applet plug-in
Industry solutions and other services
Applet developers with different scenario requirements
In the future, we look forward to working for more like
Provided by small programs such as “tiantiantong”
Solid and reliable capability support
Help all developer partners
Just like “China Star”, it shines in the starry sky of all walks of life!
