From the day I knew Dr. Cuong, I felt like I was revived, in the past I was often stressed with my children. But now it is easier to raise children for me, my children are also better, healthier. Now, I'm very happy to learn on the app.

Since having the Onllearning app, my child's learning has become much more convenient, not only that the course has been improved and many new courses have been updated, many thanks!

I have been a parent of Golden Period for 1 year now, before I learned through the web, now I have been transferred to a very convenient learning app. I am letting my children learn Bibo English here, the app works very stable and professional. Many thanks to Dr. Nguyen Duy Cuong and the Golden Period team for creating maximum conditions for children.

Thanks to Golden Period, my son has been able to communicate in English since he was a child while my wife and I have lost all our grasp of English. Seeing it makes us very happy and grateful to Dr. Cuong.
