I ordered 360 standard sentences in Chinese conversions. Service rendered by this book shop is fantastic. Just in a day gap I received it in nicely wrapped pack. I am so happy that I received it on time to complete my home work. I am at Colombo University doing external Chinese lesson. I will order more books from NIIBS Book Store. Most reliable place. Ordered book will be delivered to your door step. Thank you. 🙏🏽🙏🏽🙏🏽
