Hello, it's my pleasure to serve you. Walnut programming is true. Walnut programming, established in August, 20 17, mainly provides online children's programming teaching services and course products. At present, Walnut Programming has completed two rounds of A financing in June 20 18 and February 20 19, with a total amount of over 200 million yuan. But there are too many advertisements at present, and many consumers complain. If you want to buy a course, think carefully. Thank you. I hope it helps you, huh?
