Chanting "Tell us the truth", they said they wanted the Malaysian prime minister to apologise for what they regard as misleading statements.
Eight ships and nine planes searched around 252,000 sq km (97,000 sq miles) of ocean for debris on Sunday.
The Beijing-bound plane disappeared on 8 March with 239 people on board.
International investigators have concluded that, based on satellite data, the missing Boeing 777 crashed somewhere in the southern Indian Ocean.
The search zone shifted on Friday after further analysis. But while aircraft continue to spot debris in the water, nothing recovered by ships has so far been verified as being from the plane.
Some relatives of the 153 Chinese passengers on board Malaysia Airlines flight MH370 have refused to accept the Malaysian account of events and blame the authorities.
On Sunday, several dozen family members travelled from Beijing.
After landing in Kuala Lumpur they held a news conference at a hotel holding up banners that read "We want evidence, truth, dignity" in Chinese, and "Hand us the murderer. Give us our relatives," in English.
Their designated representative, Jiang Hui, said they wanted the Malaysian government to apologise for the initial handling of the disaster, as well as for Prime Minister Najib Razak's earlier statement that indicated the plane had crashed with no survivors.
He said the conclusion had been announced "without direct evidence or a sense of responsibility".
He said the group wanted to meet airline and government officials face to face - although he stopped short of saying that these included Mr Najib, as some relatives had earlier suggested.
None of the objects retrieved by Haixun 01 or HMAS Success is thought to be from the missing plane
Before the relatives travelled to Kuala Lumpur, Malaysia's acting Transport Minister Hishammuddin Hussein said the search for survivors would continue.
"The hardest part of my job is to see the families," he said. "I've always said we are hoping against hope that we will find survivors."
On Sunday, Malaysian officials cancelled their daily update on the search for a second day.
The objects recovered by Australian naval ship HMAS Success and China's Haixun 01 on Saturday had been examined and were thought to be fishing equipment and other flotsam, the Australian Maritime Safety Authority (Amsa) said in a statement.
An Australian vessel carrying a US device known as a "towed pinger locator" is due to join the search in the coming days.
The device is designed to detect any ultrasonic signals - "pings" - from flight recorders and can operate up to a depth of about 6,000m.
But the search area is huge - covering some 319,000 sq km (123,000 sq miles) - and time is running short. The flight recorders' batteries are expected to run out in about a week's time.
The current search area is about 1,100km (700 miles) north-east of the previous zone.
Officials said the focus changed after radar data showed the plane had been travelling faster than previously thought, thus burning more fuel and reducing the distance the aircraft could have travelled.
Various theories about what went wrong have been suggested - including the captain hijacking his own plane.
The speculation was fuelled by reports that files had been deleted on the pilot's home flight simulator.
However on Saturday Malaysia's transport minister said investigators had found "nothing sinister" from the simulator.
Malaysia Airlines Boeing 777 vanished less than an hour after taking off from Kuala Lumpur.
The airliner diverted off course and lost contact with air traffic controllers between Malaysian and Vietnamese air-traffic control areas.
my opinion :
MH370 flight search until now still not produce satisfactory
results . I think in this case, Malaysia as a country where the plane was
coming , is still hasn't shown full responsibility .
It can be
seen from the searching process , we can see that the fleet is derived mostly from
other countries . if there is no country like Australia which sent aid , or
Indonesia are often troubled with this country , even kind enough to try to
help , maybe Malaysia will not be able to search for the plane .
The problem that happening is the crux news about where the plane now , because the Malaysian government does not fall directly within the mission , but the other team , so that malaysia only receive
information without knowing the facts on the ground directly .
That's why , the people of China as the country with the most number of citizens
in the ill-fated aircraft , especially the victim's families , no longer
trust the press conference that regularly held in Beijing by representatives
of Malaysia.
This
will not happen if Malaysia participated directly, like send their fleets. They will tell everything exactly as they themselves see the real situation.
They
assume the information that given by malaysian delegation in beijing always repeated
and deemed not fit the facts. now malaysia looks like mocked on
valid information by the parties who assist in MH370 search mission.
