(Reuters) - Chinese auto dealer Dah Chong Hong Holdings (1828.HK) amassed so much inventory this year that it would take 63 days to sell all of its Bentleys, Toyotas and Isuzus, up from the 42 days' supply it carried in December. For rice wine maker Shanghai Jinfeng Wine Co (600616.SS), a 14 percent inventory increase plus slowing demand means it would take 22 months to clear stockpiles at the current sales pace, compared with nine months at the end of last year, Thomson Reuters data shows.
