May I help you ?   Yes . I'd like to send this parcel to Changchun .   How do you want to send it ?   I guess I'll send it by airmail .   Is there anything valuable ?   No , there are only some vases .   They are fragile articles . They must be packed in a proper strong box . Your light cardboard box won't do .   Have you got boxes for sale ?   Yes .   Is it all right this time ?   Yes . Now fill in two customs declarations and one despatch note in English . You'll have to take your parcel to the next window for examination when you have completed the forms .   OK .   Have you written down your return address ?
