Master Han looked at his son-in-law's astonished expression and added, "Don't think that the 711 radar is outdated, many meteorological bureaus didn't start using it until '85. Even now, it's still the main observation equipment for many city and district-level meteorological stations!"
Han Yu asked skeptically, "Are there still many units using it now?"
"Do you know how expensive advanced meteorological radars are?"
"How expensive?"
"A U.S. company quoted over four million U.S. Dollars per set, which is over thirty million RMB. Hui'an had a company last year that negotiated with that American company to introduce the technology for production. They suggested buying parts back for assembly, but even buying parts for assembly is more expensive."
