The Spring Festival is coming, so we will have a holiday during 13th to 16th, Feb. For these 4 days, we will be online from 2:30 to 5:30 in the afternoon for Chinese time. If there is any inconvenience for you, really sorry for that. If you have any problems, please leave message on our livechat or send email to us. We will reply to you as soon as possible. Thank you.
