As Bill said, ZHL is a notorious purveyor of knock-off model kits based on western designs. Definitive evidence of ZHL's theft of intellectual property can be read in this article published by the Nautical Research Guild. ZHL is on the list of banned dealers maintained at Model Ship World. Be advised, not all modeling communities share MSW's stance on protecting intellectual property -- ZHL has many defenders who do not truthfully represent what the company does, i.e. prey on the work of others, thus depriving them of the fruit of their labors.
As you may notice, this is my first post to this community, and yes -- I feel strongly enough about the kit piracy problem to register here just to spread the message: don't buy from model kit pirates like ZHL.
Cheers.
