Informed by Thaipost My Parcel EE174466720TH have left thailand from 31-Jan-2023. It is more than 20days until now not yet reach China. Where is my parcel? What is going on?

Tracking no. is EA928400572CN
and the last status show at "Arrived Guangzhou airportChuLi ZhongXin （ Transit ）,Guangzhou," on 18/03/2020.

What's that mean?
My parcel is still in China or on the way to Thailand?
How many days (from today) my parcel reach to Thailand?

To whom it may concern,

My name is Nunnapas and I am from Thailand. I have sent a parcel from Thailand to Beijing, China since January 5th 2021.
It’s been 2 months now. I heard that the consignee didn’t receive my parcel. I contact Thailand Post office but they said since it is an airmail, they are unable to track it because it has no tracking number available for this kind of airmail shipping. It usually takes 2 weeks to delivered. Thailand Post asked me to contact local post in Beijing but I don’t know how to contact you guys. I did found this email on the google so I’m trying to asking for help here.

This is only information about a parcel I have :
Congsignee : Kevin Chungkai Yang
Phone number 15101530613
Room 102, Unit 4, Building 37 Warwick North residence
Chaoyang District, Beijing, China 86
北京市朝阳区华威北里37号楼4单元102室
杨重凯 15101530613

Could you please kindly track it for me from these information? I would be appreciate it a lot and I am looking forward to hearing from you.

Best regards,
Nunnapas
